Peewee's Playhouse and Big Comfy Couch are alternate dimensions of Blue's Clues.Main character dressed strangely? Check. Friends who help with the learning and activities? Check. Large pieces of furniture which anchor the show? Check. Events that occur every episode? Check.
Steve's (and Steve's replacement) world is the result of him owning a handheld camera and a LOT of drugs.Who else do you think he's talking to?
Joe and Steve aren't actually brothers.They're actually secret lovers, but Steve was too terrified to come out of the closet to his young friends, that he told them Joe was his brother. Heartbroken and embarrassed of his cowardliness, he left Joe to "find himself" in college, while Joe lovingly keeps up the facade in front of the children.
Joe/Steve's powers are not only used for kid's playtime.Yes, they "skidoo" happily into artwork when the viewer is over and they are playing Blue's clues, but what they're really looking forward to is that each night after everyone else goes to bed they can skidoo into their Porn Stash.
Shovel is a young FTM TranssexualThink about it. His Viewer Gender Confusion, behavior, voice, look, etc.
Blue and her animal friends are deadThey died around the first episode Blue's brother appeared in. That explains why he didn't appear anymore and the episodes stopped aside from Blues Room. They were a fantasy of a dying Blue. Alternatively..
Steve is a very lonely, over-worked man.The show chronicles the day dreams he has while at work, of doing nothing all day but playing with a dog he doesn't have and talking to friends that don't exist. Eventually, he becomes so ashamed of himself that he feels the need to create Joe, a new resident in his own house, who he feels deserves it all more than himself.
Steve is a stonerHe always wears green, talks to inanimate objects, the kids have to constantly remind him what he was doing, and he has his "Skidoo" hallucinations too.
Blues Clues and Supernatural take place in the same continuity.Steve's house is actually Lucifer's Cage. The entire scenario is an elaborate hallucination created by Lucifer's endless years of boredom, which have slowly turned him insane. The 'Steve' Character a detached identity he has assumed as a result, and he constantly solves mysteries in a continual cycle to pass the endless eons of time.
Steve is a walking Idiot BallThink about it. If half of the things that he helps characters do needed his help every time, NOTHING WOULD EVER GET DONE. The only reason he does this is because the characters have been rendered temporarily stupid by his presence. This also explains his bizarre personality—he himself is effected by the field—and the only reason the kids are immune is because they come from the television!
Steve actually does see the clues, and is Obfuscating Stupidity.Since he's playing a game with a small child/small children (the audience), he pretends not to see the clues so that his friend doesn't feel useless. This is basically the Doylist explanation, but it also makes sense in universe (as that's usually how adults interact with children).
Steve can skiddoo into magazines, tooOh, like any guy Steve's age wouldn't given the power. Serious Power Perversion Potential.
Paprika is adoptedBecause you can't mix salt and pepper together to get a completely different spice.
Blue won at least a couple hundred bucks in the Superpower LotteryShe can create semi-sentient, shape-shifting, size-changing two-dimensional entities that execute her will (usually delivering messages to Steve, but they could be repurposed for, say, suffocation). They can also be applied to almost anything, including bubbles, your TV screen, and even in one episode sound waves! She can also skidoo into anything two-dimensional, which, if used correctly, has a lot of applications as well. In short, Blue could make an excellent super villain on the level of some of the Batman villains. We should be thankful she's so nice.
Steve is a reality warper/the world is actually an image he Skidooed intoSteve is relatively weak reality warper who can bring certain 2-Dimensional images into the real world and vice versa. When he was young, he simply drew a picture of a house and skidooed into it.
Scientific ExperimentsAll of the young animals in the neighborhood are scientific experiments that have taken shelter with human caretakers. Purple Kangaroo, Orange Kitten, Periwinkle, Green Puppy, Magenta, Blue... and the puppies are hue variations of some DNA experiment. (The puppies ALL LOOK THE SAME, except for color.) We'll probably never know why they were created, but they were apparently discarded to some sort of holographic environment with talking condiments and toys and clocks.
Blue is a Time Lady and the house is her TARDIS.The house looks bigger on the inside. Not my original idea.
Steve is a teenager who got emancipated from his parents.This explains why we never see his parents before he goes to college. Maybe Joe is younger than Steve and still lives with the parents until he moves into Steve's old house after getting emancipated or turning eighteen and not wanting to go to college.
Joe is older than Steve.Maybe he already went to college and then moved into his brother Steve's place.
Steve is an adult who waited a little while before going to college.Same thing may apply to Joe as well. Maybe Joe does not even want to go to college. Blues Room. When Steve/Mac goes to college, his brother, who is actually Terrance under the new nickname Joe, takes over, having become a nicer person since the events of Foster's Home For Imaginary Friends.
Skiddoing is an extreme application of the fact that Blues Clues has no 4th wallEver notice that whenever they skiddooed into something, it was always parallel to the camera and 4:3? That's because they new that they were on a blue screen and could scale up the background so it would fill the screen.
Blue was originally human.She was once a vain and selfish princess who lived in a castle with her servants. Until one day, a poor beggar came to the castle seeking hospitality. Blue insulted his ugliness and turned him out. But it turns out the beggar was really a wizard, and he cursed Blue to become a puppy, her servants to become talking inanimate objects and the castle to become an ordinary house. Now the only way to break the curse is for Blue to learn to love and be loved in return. And that's where Steve comes in...
The series takes place in the world of Myst and all the people are D'ni.When an episode starts, a book opens, and "You" are pulled into the world of the book, the Age where Blue's Clues exists. Steve, Joe, and Blue, when they "skidoo", are using the D'ni ability to travel to other Ages.
Steve (and Joe) suffer from severe mental disordersSteve (and Joe) suffer from severe mental disorders, and the world of Blues Clues is how they experience the real world. In reality, Mr. Salt and Mrs. Pepper are an interracial couple who care from them, and since Steve and Joe are harmless they let their children play with them (though they keep an eye on them just in case). Blue is a service pet they only imagine can do all the things she can, and the rest of the cast are items they anthropomorphize mentally. And when they "skiddo" they are merely imagining they're entering the book/picture/sand castle/etc.
