For a short they should do one where Woody and friends are accidentally left in a toy store in one of where there are Marvel action figures in the back room and would be hilarious to see toy Wolverine trying to claw his way out thinking he is made of adamantium. Spider-Man toy and friends must try to get them back home.
For a short there should be a Lucas related one with Star Wars action figures and a Indiana Jones figure, it would be amusing.
