I don't know I just randomly thought of this episode today. Its my least favorite of the Mermaid Man and Barnacle Boy episodes. Its not that I hate it, its just that SpongeBob transitioning to Fry Boy kinda annoyed me. He's the freaking Sponge of Mystery not Fry Boy: Defender of The Krabby Patty.
Otherwise, the rest of the episode was ok
I loved Plankton and probably one of my favorite quotes of Season 5.
Say, this isn't Professor Plankton's Dandruff Control Shampoo, it's Professor Plankton's Mind Control Shampoo!(MWAHAHAHAHHAAA) With conditioner.
