Spongebob Squarepants Movie, The - Getting Away Quicker
At about 41 minutes and 50 seconds, SpongeBob gets his feet stuck on "the lady" with the ice cream. About 20 seconds later, SpongeBob sees that it is a monster. A couple of seconds after that, SpongeBob bites off "the lady's arms so he can get free. However he never does anything to his feet to get them free. How did they get his feet to break away?
In the show, he's detached his limbs tons of times, and grown them back, probably did like a lizard does with its tail. Spongebobian physics for the win.
