After hearing about Guillermina and Candelario's adventures with a blackbird, their Grandpa finally finds out the birthday surprise they have in store for him.

Kevin's plans to use his relationship with Vicky to make Cata jealous are unexpectedly thwarted.

Guillermina and Candelario decide to give their grandpa a birthday surprise.

As Kevin attempts to muster up the courage to break up with Vicky, he discovers that their relationship may have an unexpected benefit.

At the dinner table, Kevin's family meddles into his budding relationship, which he is already thinking about ending.

Following her argument with Candelario, Guillermina gets pampered like a queen in a deep sea hair salon with a colorful cast of characters.

At some point, Kevin started thinking that dating Vicky would bring him closer to Cata. But things turned out differently.

Kevin feels left out when it seems as if his best friend, Fede, has abandoned him for a woman and still has his hopes pinned on Cata.

When Candelario makes fun of her hairstyle, Guillermina storms off, only to be aided by yet another fantastical creature.

Rumor has it that Cata and Casas are about to break up due to Cata's interest in someone else, leaving Kevin wondering who it could be. Meanwhile, Fede is curious about a girl rumored to have a crush on him.

After failing to triumph at the surf competition, Candelario feels a bit defeated. However, his grandfather and sister are there to console him as usual and an unexpected surprise awaits him.

At Kevin and Fede's high school, having a girlfriend is a huge factor in a guy's popularity, and, while Fede couldn't care less, Kevin seems a bit more conflicted.

When Candelario is reluctant to tell his grandfather about his experience competing in a surf contest with an extremely agile dolphin, Guillermina is quick to chime in.

In the midst of a "serious" conversation, Kevin and Fede are surprised when Cata approaches them- and even more surprised to see her sporting a pair of glasses.

Can Guillermina and Candelario salvage the concert at the bottom of the sea?
