Peg has received an enormous present, but she wants Cat nearby when she opens it. He calls her, but even he doesn't know where he is. Peg complains about not being able to find Cat, when a caterpillar asks how it makes her feel. An acorn falls on Peg and she says, "Ouch!". The caterpillar says, "Sorry it hurts", but Peg explains that an acorn fell on her. This inspires her to look up, and she sees Cat in the tree, juggling acorns. She thinks he intentionally dropped the acorn, and, while Cat isn't sure if that's true or not, he can't deny it either. The first problem is solved, but there's a bigger one: Cat doesn't know how he got there, and he doesn't know how to get down either!
So Peg leaves Cat and the caterpillar, who's still curious about Peg's feelings, and finds the Neighbor Ladies. They assume she wants clothes, but really she wants a ladder. Viv lets her borrow one, but she has to stack items that are in the way first. Peg stacks them, while singing about how to do so without them falling over, and then gets the ladder.
However, the ladder is rickety, and when she tries to climb it, it breaks. After a brief rant, Peg asks Cat what he'd do if he was on the ground, and Cat says that he would walk around until he bumped into something. Peg tries, and bumps into the box, which gives her the idea to open it. She takes out a kaleidoscope and a coloring book, both very huge, and decides to stack them so Cat could climb down. The kaleidoscope is too slippery to climb, but it's good for sliding, only it is not high enough to reach Cat. Cat suggests she look in the box again, but Peg decides to move the box instead and stack the kaleidoscope on top. Ramone, having a day off, arrives and helps Peg out, but Cat doesn't know how to get down from the box. Ramone suggests Cat jump into his arms, but Cat doesn't want to, so Peg has him slide down the coloring book instead. The title characters then sing a song about Peg's loyalty to Cat.
