Peas-in-a-Pod

The Peas-in-a-Pod is one of the toys owned by Bonnie Anderson, who appears in Toy Story 3 and Toy Story Toons. Their names are Peatey, Peatrice, and Peanelope. The peas in a pod will return in Toy Story 4 to help Woody reunite with Bo Peep and her sheep.

Toy Story 3
Woody first sees them after getting played with by Bonnie. One of the Peas-in-a-Pod ask him if he's a real cowboy, and before he gets to answer another says no he doesn't even got a cowboy hat. This causes Woody to notice that he's lost his hat.

In the end credits, the peas cause mischief inside Mr. Potato Head's body, causing a number of his parts to pop out, and Mr. Potato Head furiously warns the peas to stay out of his butt as they bounce away laughing.

Hawaiian Vacation
Peas-in-a-Pod briefly appears when Woody announces that Bonnie has gone on vacation for winter break. Later, they are seen telling everyone Bonnie is coming.

They make a brief cameo as a drawing on Bonnie's wall.

Toy Story 3: The Video Game
The Peas-in-a-Pod make their appearance with the rest of Bonnie's toys as they are around a game board set up by Hamm to tell them about the journey in the third film.
