"Make Pizza!" is an episode of Oobi from the first season.
Oobi, Uma, and Kako are looking at colored pencils when Uma's stomach begins to growl. Oobi and Kako hear this and call Grampu to make lunch. However, he is listening to music with headphones. With the help of the viewers, Oobi gets Grampu's attention. The children ask him to make some food. Grampu brings out tomato sauce, cheese, and dough. This confuses the children until Grampu explains that he is going to make pizza, and the children offer to help.
Grampu explains that they must press the dough and throw it in the air first. Grampu leaves the children to do this. They press it and throw it upwards together. However, the dough becomes stuck on the ceiling. Grampu comes in to check on them. As he does this, the dough falls back down and lands on his head.
They laugh then proceed to flatten the dough again. Grampu explains that the next step is to apply tomato sauce, and he goes to get a jar. Uma spies some tomatoes in a colander and brings them over. Oobi gets the idea to make tomato sauce by squeezing the tomatoes, with each person using a different method of doing so. Oobi squeezes it directly onto the dough, Kako presses it against Oobi and squeezed the juice onto it, and Uma repeatedly presses down in it. Grampu walks in with the jar of tomato sauce, but sees the children squishing the tomatoes and leaves. Afterwards, the children put shredded cheese on top of the pizza.
Grampu places the pizza in the oven and sets a timer. While the children wait, they tap to the rhythm of the timer. When it goes off, Grampu takes the pizza out. The children cheer and proceed to eat the whole thing. Grampu asks for a slice and Uma tells him that it is gone. Kako gets the idea to make a second pizza, which everyone else agrees with.
Grampu asks the viewers if they have ever tried pizza. After this, Oobi and Grampu are shown putting the finishing touches on their second pizza. They notice that the pepperoni has been arranged in the shape of the letter "P" and play a letter game. During the game, Uma places a stuffed penguin onto the pizza. She asks to cook it, but Grampu lies saying that he is full. The episode ends.
