Dora tells a story about her twin siblings becoming superheroes. In the story, the park is having a Banana Festival, but Swiper steals all of the bananas, including the babies' banana baby food. So the twins become the Super Babies and try to get it back. The Super Babies have special powers: X-Ray vision, supersonic hearing, flight, levitation, and loud crying.
The episode starts with Dora and Boots helping Mami feed the twin babies their banana baby food. Dora then tells them a story on how they were Super Babies. Dora, Boots, and the Super Babies were at a banana festival, but Swiper steals all of the bananas, along with the Super Babies' baby food. The Super Babies got into their stroller, and they, along with Dora and Boots, set off to get the bananas back. They had to go across the bubble bath and past the building blocks to get to the Bananas. En Route to the bubble bath, the road was blocked by a sleeping big blue baby bear. The Super Babies, along with Dora and Boots, super cried and woke the baby bear up, causing it to move out of the way. When they got into the bubble bath, they had to super pop the bubbles and to super paddle to evade a large rubber duck. Afterwards, when they had gotten to the building blocks, the Super Babies rearranged them to make stairs for the group. As they go the bananas, the Super Babies had gotten thirsty and slowed down, so they get the bottles from the Backpack. After getting a drink, the Super Babies had gone faster. Swiper was climbing up the bananas, but the Super Babies stop him. Dora, Boots, and the Super Babies then return the bananas to the festival.
