Role in series

"Chimps Ahoy"

He, along with Lord Reginald and Dr. Marmalade, leave the bus that stops at Sandy's Treedome. He introduces himself and then Dr. Marmalade and Lord Reginald. He mentions that they are the board of directors at Tree Dome Enterprises Limited. He then says that they are there to see if Sandy's intentions are good enough to give her more money. He then asks who SpongeBob and Patrick are. SpongeBob says his name and Patrick calls himself, "Professor Patrick." Professor Percy then asks where Sandy is. SpongeBob tells them that she will be back at any moment.

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 the invention and then proceeds to start the machine. Professor Percy asks if Lord Reginald is alright.

The invention works fine, but eventually malfunctions and starts attacking Lord Reginald. Professor Percy asks "Professor Patrick" what the meaning of this is. Patrick then replies that the screaming means that it is working. Sandy hears the screaming and runs into the treedome. Soon, Lord Reginald is shot out of the invention. Professor Percy asks if Lord Reginald is alright. The three decide to stop Sandy's funding.

One of Sandy's inventions, the Fully Automated Nutcracker, starts up. It is laying on a log nearby and takes the banana and peels it. Dr. Marmalade is surprised. Professor Percy tells Lord Reginald to test it again. Lord Reginald takes out a banana and it peels it. The board of directors says that it must be the banana peeler that they have been searching for over a hundred years for.

They start acting like animals who are excited. Before leaving, Sandy's bosses take back what they said about her losing her funding and they give her another 20 years of funding.
