After the events of the episode, he returns to the meatloaf with new-found interest and begins "eating" it enthusiastically.
It is a light brown, live-action meatloaf, with various live-action vegetables around it. It is shown on a white plate, and is, of course, holographic.
Plankton stated that it was the only thing he could eat, due to his lack of money, and eats it with a fork. At first, Plankton dislikes the meatloaf, most likely because it shows how unsuccessful he is, and has failed again in obtaining the Krabby Patty Secret Formula. He slams it off the table to show this.
"Oh goodie, holographic meatloaf, again. When am I gonna get some REAL food. Mr. Krabs gets to eat real food, just look at his daughter! She's as big as a whale!" —Plankton
