It is Gugu’s birthday and Nana decides to make him a cake. However, as she tells her friends what she is about to do, everyone wants to prove that they are in fact Gugu’s best friend and each one of them sets out to make their own cake.

Nana's kite has got stuck in her house’s roof. As she goes looking for help from her friends, she ends up helping them instead. As she's feeling down, Gugu makes her understand that helping others is a way to help ourselves too.

Pepe is playing with a flipped bucket as if it were a drum and Lili decides to join him. Soon, Toto comes by and also wants to join them as well. Suddenly, they hear that someone else is playing in the distance, and they discover that it's Nana and Gugu.

Lili is really bored and she goes looking for her friends, but everyone is going through a difficult situation. Gugu will help her understand that we may feel bad from time to time, but it's not a permanent situation.

Toto is walking in the forest and he sees some bushes moving suspiciously. He's found a Monster! Scared, he runs off looking for his friends. They then decide to compare the information to figure out what is hiding in the bushes.

Toto invites all his friends to play at his house. Nana happily accepts, but asks if her friend Quique can go too. When they all arrive at Toto’s house, they realize that Quique has an injured wing.
