Role in series

"Chimps Ahoy"

He, along with Professor Percy and Lord Reginald, leave the bus that stops at Sandy's treedome. Professor Percy introduces himself, Dr. Marmalade, and Lord Reginald. SpongeBob and Patrick show the three their invention, the Automatic Back Scratcher, Hair Comber, Nose Picker, and Ukulele Tuner 9000. The three are unimpressed and want to see a demonstration of the invention to see if it works. Patrick chooses Lord Reginald to test it out. The invention works fine, but eventually malfunctions and starts attacking Lord Reginald.

Sandy hears the screaming and runs into the treedome. Soon, Lord Reginald is shot out of the invention. The three decide to stop Sandy's funding. Dr. Marmalade then says that he is starting to question the economic benefits of underwater treedomes. The three are about to leave when Dr. Marmalade says that the excitement made his potassium levels reduce. He takes out a banana. One of Sandy's inventions, the Fully Automated Nutcracker, starts up. It takes the banana and peels it. Dr. Marmalade is surprised.

They start acting like animals who are excited. Sandy's bosses take back what they said about her losing her funding and they give her another 20 years of funding. The three primates then leave.
