The main hook of Scribblenauts is that you can write ANYTHING, so of course, this page would be compulsory. Just to give you an idea, you can write any kid-friendly, non-proper noun (even some proper ones like Cthulhu, Albert Einstein, and Longcat) on the touch screen, and the object written is spawned. The game's dictionary is its greatest asset, and the dev team has repeatedly assured gaming websites that they are thinking of everything. It's become standard form in interviews with them to ask them a random collection of nouns to find out if they're in, or being put in, the game. They've been hit with things like "dialysis machine" and a specific kind of cooking pot. With the exception of vulgar things, trademarked characters (for obvious reasons), and abstract or really, really, really obscure nouns, they haven't been caught off-guard yet. (One reporter apparently stumped it with "pillory," but he notes, "That tends to get used more as a verb anyway.")
Check out this story (somewhat NSFW). In short, "I FUCKING TRAVELED THROUGH TIME AND JUMPED ON A DINOSAUR AND USED IT TO KILL MOTHERFUCKING ROBOT ZOMBIES."
The Devs got wind of that famous post, and "Feep", "Post Two One Seven" and "NeoGAF" were all plugged into the game before its final release.
When someone actually stumped the dictionary at E3 with "Plumbob"note it may have been misspelled anyway, the dev watching the playtest got on his cellphone, chatted with someone else on the dev team, closed his phone, and told the playtester that the word would be in the final release.
And yes, you can summon a Starite, but you can't actually clear the level with the phony Starite. Sorry. (Except in one level, where it's the only way to beat it)
If you time travel while holding milk, the milk will become cheese.
Animals and other creatures all have certain foods they will and will not eat. Goats eat clothing, zombies eat most body parts, cats eat fish, etc. Cows will eat beef... and contract mad cow disease and become aggressive. Pigs will eat most food items, but will become "heartbroken" if you present them with ham or bacon.
Strangely enough, a mayor will actually eat a LOLWUT (A giant version of Maxwell's head). This is exclusive to the first game only.
Some people and animals are afraid or angry at other things. Cats will fight rats. Cats and dogs will fight each other. And Rabbis will run from bacon.
Priests will eat ham, but rabbis and imams won't.
Wrestlers will fight other wrestlers, and boxers will fight other boxers.
Elves and Dwarves would fight each other.
Two rabbits in close proximity will, well, breed like rabbits. In a demo version, the rabbits wouldn't stop making more rabbits, which led to them crashing the game by making too many for it to handle. This was fixed, though.
"Game of the year," "Innovation," and "Game of the century" all make a copy of Scribblenauts.
If you try to recreate what Maxwell is riding in the boxart of Super Scribblenauts (Winged Polkadotted Bathtub), the game will give the wings a purple tint like in the art, because you can't change the color of the wings.
But you can trash those wings and replace them with striped wings.
If you spawn a kappa, he will attack you. If you give him a cucumber, however, he will become friendly — just like in the original legends.
One level spoofs The Wizard of Oz; you can give the characters what they want (a heart, a brain, "the nerve", and a home), but they will also accept what the Wizard literally gave them in the movie — a diploma, a watch, a badge, and a hot air balloon. Also, ruby slipper and silver slipper works for the girl. (The silver slipper is from the book.)
And of course, you can make witches. Both a bucket of water and burning at the stake can take them out.
Additionally, in Unlimited, typing "Your Mom" summons a zombie.
Typing in "Massive Damage" summons a giant enemy crab. There's even a level about it and Samurai will instinctively attack it.
In Super Scribblenauts, if you apply an adjective related to the seven deadly sins to anything, God will attack them - for instance, try summoning a proud, gluttonous, or lazy person.
Obviously, an invisibility potion can make the person or creature drinking it invisible. However, you can create a "visibility potion" that will render an invisible creature visible.
In the third game, while in Edwin's Farm, normally your sister Lily is un-selectable, cannot be killed, and does not react to objects or creatures. That is, unless the creature or object petrifies things. In which case Lily freaks out. Because you just saved her from the same fate.
Scribblenauts Unlimited is an attempt to cover up the few rare moments where the developer DIDN'T think of something, or couldn't do something because of legal concerns. You as a player can make your own items for Maxwell's notebook dictionary, or download items from the Steam Workshop.
The time traveler, who looks a lot like Marty McFly, will get on a hoverboard.
Giving a ring to a halfling (hobbit) will cause it to turn invisible.
One challenge in Super has you using adjectives to create cavemen resembling prehistoric reptiles. Making a "feathered caveman" for the deinonychosaur works.
You can summon Fenrir in Super Scribblenauts (it potholes to "werewolf"). Summon Odin, and the two will attack each other. Fenrir wins.
Nuckelavees are afraid of rivers. Starting in Super, they also poison cows with their mere presence.
One challenge in Super presents you with a 4x4 grid of boxes. Each box contains a trait found in various animals in addition to a light. Summoning an animal will make the lights glow in the boxes that contain features found in that animal. Your goal is to turn the lights on in four consecutive boxes twice (you can only spawn three animals). Making a platypus will turn the light on in the poison box.
Basilisks/cockatrices run in fear from weasels, roosters & mirrors. One challenge in Unlimited has you defeat one; any one of those methods will work.
