Steven is at the Big Donut shouting in despair after finding that Cookie Cat has been discontinued due to a recent competitor, Lion Lickers. Sadie lets him take the freezer it was originally sold in. When he gets home, he finds Amethyst, Pearl, and Garnet locked in battle with Centipeetles that have invaded Steven's room. They destroy most of them, but have not found the gem that normally appears with enemies. Garnet believes there's a mother Centipeetle somewhere. Steven shoos one from the fridge and finds many Cookie Cats in the freezer. The gems explain how they got some from a nearby factory. He is so happy he begins to sing the Cookie Cat theme song from a television advertisement. He then takes a bite out of a Cookie Cat, and his gem starts to glow. Amethyst tells him to try to summon his weapon, but Steven does not know how. Eventually the Gem stops glowing, and Steven is sad. He asks to be taught how to summon a weapon, and Pearl volunteers to show him first.
She takes him to a tree with many petals, and tells him that each petal falling to the ground is moving precisely in accordance with the Earth around it, and that this can be mastered by training hard. She then summons her spear as a demonstration. Steven picks a handful of petals, but is utterly confused. Steven then goes to Amethyst, who is behind the Big Donut. Amethyst explains that whenever she needs her weapon, it comes to her. She demonstrates by pulling out her whip and slicing a dumpster in half. Steven is confused by this, because it is the opposite of what Pearl told him. He visits Garnet last, on top of the Crystal Temple. He asks if he has to train hard and not worry at the same time, to which she replies affirmatively. She tells him the alternative is to connect with all living matter and energy around him, which is her method for pulling out her gauntlets. Steven remains utterly confused.
Steven decides to do it his own way, by recreating what happened when his gem started to glow. He attempts to make everything exactly as it was before, and sings his song again. This fails, and he thinks he is not cut out to be a Crystal Gem. The others think he is being silly, and reassure him that he is one of them. He eats another Cookie Cat, when his gem suddenly starts glowing brighter than it did before. It glows to the point where his weapon is finally revealed: a shield. The others bask, and Steven yells in happiness. His shield starts bouncing around the house and smashes into a TV, which Amethyst finds hilarious.
Steven thinks that he can summon his weapon by eating ice cream. When Pearl looks at the wrapper, wondering what its ingredients are, the ground suddenly starts rumbling, and the mother Centipeetle appears outside. Amethyst, Pearl, and Garnet go outside, but they tell Steven to stay inside. They engage in battle, but Steven grabs the Cookie Cat freezer and many Cookie Cats, and goes outside to help. The Gems are trapped, apparently losing. Steven captures its attention and eats a Cookie Cat. However, he fails to summon his weapon and runs away. He desperately eats the remaining Cookie Cats, wondering why it's not working. When he sees the Cookie Cat freezer is damaged, he is distraught and gets a new wave of courage. He grabs it by the plug and throws the broken freezer at the mother, electrocuting it. The Gems then defeat the mother, and Garnet bubbles its gem, sending it to the temple.
Steven buries the wrappers and cries a little. With the aid of the Crystal Gems, he resolves that he is unable to summon his weapon by eating ice cream. Then the gems cheer him up by saying that he'll be able to figure it out, "in his own Steven-y way". He then says he might have ate too many Cookie Cats and then Pearl and Amethyst laugh. Before the iris closes in on him, he throws up.
