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 super 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 swipes all of the bananas, along with the Super Babies' baby food and throws them very far away. The Super Babies got into their stroller, and they, along with Dora and Boots, set off to get the bananas back. The problem is that they don’t know where to go to find the bananas, so they ask Map for assistance. He says that the banana baby food is on top of a huge mountain of bananas. But before they can get there, they had to go across the bubble bath and climb up the building blocks. They couldn’t find the bubble bath, and all of a sudden the super babies use their super hearing to find it, there are three trees, behind the first tree is a frog croaking, the second tree is the sound of bubbles popping and the third tree has the sound of a squeaky toy. The viewer finds the bubble bath behind the second tree. So they got going. 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 use their super breath to blow an inflatable boat to ride across the tub. As they got going, they had to super pop the bubbles and to super paddle to evade a large rubber duck. Afterwards, they had to find the building blocks, but a giant rock is in the way. The Super Babies use their super x-ray vision to see inside the rock. Sure enough, they found the blocks. When they had gotten to the building blocks, the Super Babies rearranged them to make a staircase for the group. The first step has one block, the second has two blocks, the third has three, fourth has four, and fifth has five. Now, they have to find the bananas. The super babies use they super strength to lift the stroller high enough so they can get a better look. Sure enough, they see the bananas. Along the way, the see a giant hole in the middle of the road, so the babies decided to make the stroller fly. But all of a sudden, the Super Babies had gotten thirsty and slowed down, so they get a drink from the Backpack. They can’t drink from their rattles or their diapers, so they get two baby bottles out of the Backpack. After getting a drink, the Super Babies had gone even faster. They made it to the banana mountain. Swiper was climbing up the bananas (even with him disguised as a walking banana), but the Dora, Boots, and the Super Babies stop him from swiping and eating the banana baby food. "Swiper, no, no!", yelled the babies, and then Swiper slipped and fell on the bananas and he slid down. Dora, Boots, and the Super Babies then return the bananas to the festival.
