The Simpsons: Bart & the Beanstalk (1994)

Once upon a time... Bart Simpson had a cow, man. He traded it for some magic beans which grew into a giant beanstalk. If he can scale the stalk, overcome giant bugs, mash monstrous mice, and grab the Giant's loot, he'll become a zillionaire faster than you could say "I DIDN'T DO IT!"
