Mario and the Beanstalk / Bats in the Basement

Desperate for cash, the Marios trade the royal cow for bean seeds. Princess scolds them, and accidentally sneezes, blowing the beans into the yard. Overnight, they grow into a beanstalk. The next morning, Mario and Co climb the beanstalk, which takes them to a gigantic castle in the sky, which is occupied by Koopa, who's now giant-sized.
