Evil Pea launches Supertato down the back of a sofa, but her plan goes wrong when she falls in too. Stuck inside with no obvious way out, they meet kooky Raisin, who lives down there with her collection of buttons. Raisin shows them the only way out of the sofa – a thread hanging from above. But Evil Pea climbs up first and undoes the thread, leaving Supertato trapped. Inspired by Raisin and her buttons, Supertato uses them, along with the thread, to create a pulley system to get out.
