Marshmallow Muscles Larry was told that a certain muscle cream was the newest best thing on the market and claims to
double a person's muscle power when used as part of a muscle-building workout. Interested in this
product, he buys the special muscle cream and recruits Patrick and SpongeBob to help him with an
experiment. Larry develops a special marshmallow weight-lifting program for Patrick and SpongeBob.
He meets with them once every day for a period of 2 weeks and keeps track of their results. Before
each session Patrick's arms and back are lathered in the muscle cream, while Sponge Bob's arms and
back are lathered with the regular lotion.
