Anchor Arms are a pair of inflatable, rubber fake biceps that SpongeBob wears in the episode "MuscleBob BuffPants."


Anchor Arms appear to be long, large pink balloons that are worn on the arms like gloves and inflated to form "muscles."

The settings are as follows:

  • Normal
  • Strong
  • Veiny
  • Hairy (for the "ladies")

The levels of air pressure are as follows:

  • Normal (Green)
  • Strong (Yellow)
  • Super (Orange)
  • Jerk (Red — Never inflate to this level as it will cause over-inflation and damage the Anchor Arms. However, SpongeBob eventually blows them exceeding Jerk as he struggles when lifting his anchor, causing them to overstretch, explode, and deflate.)

Role in series

"MuscleBob BuffPants"

SpongeBob, coming to a conclusion that he is very weak, buys a pair of Anchor Arms after having seen a commercial for them, with the intent to impress Sandy with his "strength." He goes to Goo Lagoon to deceive everyone with his fake muscles, with everyone buying it. Thinking that he is really strong, Sandy signs him up for an Anchor Toss competition.

When it is SpongeBob's turn to go, the Anchor Arms' rubber starts to stress due to SpongeBob overinflating them into the 'Jerk' size while struggling to lift the anchor. Eventually, they explode and deflate, revealing his "muscles" to have been fake.


There is some graffiti on the side of Larry's Gym that reads "Anchor Arms are for wimps."

Revenge of the Flying Dutchman

They can be seen in the GameBoy Advance Version for one of SpongeBob's wishes.

Battle for Bikini Bottom

A variant of the Anchor Arms is used to repair SpongeBot SteelPants, after the real SpongeBob temporarily destroys him. The difference is that these particular Anchor Arms appear to be made of plastic, instead of rubber balloons as in the original.

SpongeBob's Book of Excuses

One of the excuses is Sandy asking SpongeBob why he has fake muscles; SpongeBob replies that "the muscles are real, the rest of [him] is fake."

Anchor Arms is mentioned on some graffiti found on the side of Larry's Gym.


  • 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.
  • In the scene where the Anchor Arms blow up, they are then deflating in a similar manner as a rubber balloon — floating randomly as they lose air and making a characteristic noise.
  • SpongeBob appears to hide his real arms inside his body while using the Anchor Arms, as seen after the Arms get destroyed, he pops his arms out as Sandy looks at him.
