Role in episode
Plankton called the Bogus Business Bureau to complain that Mr. Krabs would not let him guess how many bun seeds were in a jar for the annual bun seed guessing contest, in which the winner receives a free Krabby Patty. Twirp went to the Krusty Krab, demanding that Plankton be allowed to guess or the Krusty Krab would face being shut down.
When Mr. Krabs says Plankton's guess of 500,301 was incorrect, he is ordered by Twirp to count every last seed to prove it, but it turns out Plankton was right.
Despite standing up for Plankton, he also upholds Mr. Krabs' rules, saying he would allow a show before Plankton received his Krabby Patty, and that Plankton had to eat and swallow the Krabby Patty on the premises.
