The inability to cosplay as WALL-E or EVE puts a damper on its fandom. No one wants to leave the house looking like this. However, that doesn't stop fans from taking pictures with a real-life WALL-E at the Disney Convention, or making a working WALL-E of their own.
If robotics engineering is a little out of your wheelhouse, there's a lovely series of WALL-E action figures, from miniature versions of your favorite characters all the way up to a WALL-E you can talk to.
If humanity flees our garbage dump of a planet but you miss the memo, you'll have a friend to spend time with: just you, your WALL-E, and some cheery cockroaches. Stock up on Twinkies!
