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. Professor Percy then asks where Sandy is. SpongeBob tells them that she will be back at any moment.

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.
