The Sonic Storybook Series is a series of spinoffs to the Sonic the Hedgehog franchise, whose stories are modeled after classic literature, with Sonic and friends as main characters of the story.So far, two entries in the series have been released on Nintendo's Wii console:
Sonic and the Secret Rings (2007), based on 1001 Nights: Came about due to the time issues with attempting to port Sonic the Hedgehog (2006) for the Nintendo Wii, in time for launch.
Sonic and the Black Knight (2009), based on the legend of King Arthur.
Taken for Granite: Gargoyles in Secret Rings and and fish-like Knights of the Underworld in Black Knight are capable of turning Sonic to stone. Oddly enough, it's instantly fatal in Black Knight without the Stone Brooch or Petrification immunity equipped, but is not fatal in Secret Rings — you just have to shake the Wii Remote to break free.
Sonic himself does end up playing a role of one of the characters, though he retains his own personality regardless. It's implied in Sonic and the Secret Rings that Sonic is standing in for Aladdin; in Sonic and the Black Knight, it's revealed in the ending that Sonic is the true King Arthur (the one fought earlier was a fake created by Merlin.)
Because You Were Nice to Me: This was likely the reason why Shahra sacrificed herself for Sonic's sake and did not jump to Erazor's defense whilst he was dooming him to his eternal prison. Sonic was probably the first master who treated her with genuine kindness and concern, who didn't disrespect her or treat her like magical property who can fulfill his wildest dreams.
Body Horror: The horrifyingly painful transformation Erazor goes through when he absorbs the world rings.
Book Ends: Sonic's first and last wishes are for handkerchiefs.
Bottomless Pits: Levitated Ruin appears to consist of mostly this, but it's actually pretty hard to fall off due to invisible walls. Oh, you can lose rings alright...
The Cameo: Big the Cat can be spotted in all of the levels in the game. To trigger his appearance, you have to stand still in a specific spot on the level for a couple of seconds. You also get a page of his diary whenever you do so.
Chekhov's Gun: The item Shahra gives Sonic after gaining the World Ring in Levitated Ruin turns out to be Erazor's lamp, which he turns on him in the ending.
Dark Is Not Evil: Darkspine Sonic, the form Sonic takes after unintentionally absorbing the World Rings of Sadness, Rage and Hatred. Whilst his appearance gives off vibes of great evil (Purple-Indigo color scheme, No Mouth, blank pupil-less Glowing Eyes of Doom), this definitely isn't the case regarding his personality and actions. Whilst undoubtedly vicious, Darkspine acts entirely in the interests of the Arabian Nights and even seems to be insecure as he begs for Shahra's power and calls out to her during the battle against Alf Layla Wa-Layla.
Defiant to the End: Erazor's attitude even as he is being sucked into his lamp for eternity is to try and talk Shahra into stopping Sonic and he even insults Sonic by calling him a dirty rat. He even boasts about how the world belongs to him.
Extreme Melee Revenge: Darkspine Sonic does this to Alf Layla wa-Layla after seeing his only companion in the entire game get temporarily killed. He beats the crap out of Alf Layla furiously with his bare hands.
Final Boss, New Dimension: The fight against Alf-Layla-wa-Layla takes place in a giant black void. Considering that at this point, all but the last few pages of the Arabian Nights have been sucked dry, this makes sense.
Fire of Comfort: Sonic's (Presumed) house has a pretty comfortable-looking fireplace.
Fog Feet: Shahra appears like this for most of the opening cutscene.
Levels Take Flight: Levitated Ruin is set on a flock of rukhs. The stage gets its name because they carry the ruins of small cities on their backs.
Light Is Not Good: Alf Layla wa-Layla note the form Erazor Djinn takes after his botched attempt at sacrificing Sonic's life (resulting in his inability to properly control the World Rings was formed by Erazor absorbing the World Rings of Prayer, Joy, Pleasure and Wishes.
Literal Genie: Shahra is actually this, as shown by Sonic's first and third wish. It's less noticeable because Sonic is probably Genre Savvy, and definitely doesn't care.
Morton's Fork: Basically, no matter what Sonic does, he'll lose. Either he gives the World Rings to Erazor hoping to have his flame arrow removed whilst juggling with the idea that Erazor will use him as a sacrifice to gain true control of the Rings, or he doesn't and the flame arrow kills him anyway. Lucky that Shahra threw a wrench into his works via self-sacrifice, preventing Erazor gaining true control of the World Rings and bringing about a series of events that ultimately worked in Sonic's favor.
Mundane Wish: Sonic's first wish after being asked what he wants by Shahra? Handkerchiefs. Though to be fair, he was in desperate need of some at the time because of a sneezing fit caused by a cold he had come down with a day before.
He makes this same wish in the end, when Shahra is in need of them.
Nintendo Hard: The later missions are all insanely hard, and mostly consist of the Avoid the Pearls/No Damage/X Ring Chain variety with crazy obstacles. They're optional, however.
Oh Crap: Erazor when he realizes that Sonic has his lamp and thus can force him to grant him three wishes.
One-Winged Angel: Erazor has a rare non-inflicted version happen to himself when he absorbs the World rings.
Open Sesame: Sonic tries uttering this at the World Ring door. It doesn't work.
Sealed Evil in a Can: Erazor was sealed inside his lamp by King Solomon some time before the story starts. He manages to escape after granting the wishes of one thousand people, just to cause even more mayhem. Sonic manages to reseal him inside his lamp and finish him off once and for all.
After the initial Lost Prologue missions, where Sonic takes a flaming arrow to the chest for Shahra.
Right before the final fight, where Shahra takes a fatal blow from Erazor's sword to protect Sonic.
The Gloves Come Off: Darkspine Sonic's entire attitude when it comes to fighting Alf Layla Wa-Layla. Not only does he look like Shadow with his quills down, not only does he kick a giant blue ball of Arabian Nights back at his opponent, not only does he pummel the transformed Djinn in the protruding heart with his bare hands, but he does not wear gloves.
The Power of Hate: One of the World Rings Darkspine Sonic used to transform was the Green one, which contains hatred. Therefore, Darkspine is effectively powered by hatred. Considering Erazor just murdered Shahra, Sonic's got plenty of that.
The Worsening Curse Mark: The size of the flame on Sonic's chest is directly proportionate to how much time he has left until it extinguishes along with his life force. Near the end of the game, it is tiny.
Continuity Nod: Black Knight has a few instances in the levels where Sonic talks about past experiences that that something reminds him of.
Crush Blush: Percival (Blaze) blushes lightly after Caliburn says "Save the hugs and kisses for later" towards her and Sonic.
Crying Little Kid: Played with. Sonic does stumble across a child weeping over her parents and fellow townspeople being kidnapped by a dragon, but it turns out that the child is really Nimue in disguise, employing a test to see what Sonic would do. He passes with flying colours.
Excalibur in the Stone: Subverted: It seems that the two are separate swords at first, but then it's revealed that Caliburn (which Sonic has been carrying around the entire game) is actually the true Excalibur.
Mythology Gag: When you are on the character select screen right before starting a level in one-player mode, Sonic's thumbs-up pose looks very similar to his official render in Super Smash Bros. Brawl.
No Ending: The story just sorta stops after the final battle with the revelation that Sonic is King Arthur or at least his story book equivalent. Whether this was meant as a Sequel Hook or not remains to be seen, but that's not how it ends.
Noob Bridge: The Will-O-Wisps are glowing blue orbs of energy that explode and can hurt you when hit. You're supposed to use the "kick" mechanic to kick them into things. Thing is, that mechanic is only really used twice in the main game, and those instances are easy to miss, so you might not even know you can when you find the Wisps much more often in the post-game.
Standard Status Effects: Paralysis will prevent Sonic from being able to move temporarily, poisoning will cause ring drainage, freezing has the same effect as payalysis except you have to break free of the ice, petrification equals instant death, and confusion will make Sonic occasionally hallucinate and see enemies as treasure boxes and vice-versa.
Suspiciously Similar Substitute: Played with. Merlina is obviously this to Shahra from Secret Rings, and is made out to fill a similar role in the story. Then it turns out she's the game's main villain.
Technicolor Toxin: When a character is poisoned, purple bubbles will appear around them.
Videogame Caring Potential: You can give rings to the townspeople (providing that you have 20 to give) and in return (if you succeed on the Quick Time Events) said towns-person will give you an item. Doing so will also add to the Knight's Honor bonus.
Videogame Cruelty Potential: You can actually attack the innocent townspeople. Doing so has a negative impact on your score however and can saddle you with negative titles.
