Role in the series

MuscleBob BuffPants

SpongeBob notices that he is week compared to Sandy and she offers to give him exercise training. After failing at it, SpongeBob goes home with painful arms. He lies in his arm, when a commercial on TV starts. Donald the Shark tells the audience why to buy the product. SpongeBob is then convinced and buys some. He goes to Goo Lagoon to show off his muscles. He convinces everyone, including Sandy. Thinking that he is really strong, she signs them up for an Anchor Toss competition. When it is SpongeBob's turn to go, the Anchor Arms start to malfunction due to SpongeBob's straining to lift the anchor. Eventually, they blow up and it is revealed to everyone that they were fake.

Battle for Bikini Bottom

A variant of the anchor arms is used to repair SpongeBot SteelPants, after the real SpongeBob temporarily destroys him.


  • It is a reference to part of an anchor called the "arm," which is the part that curves out from the bottom end of the main part and ends in the pointed part.
