She has her first major role in "Croaked". Sid and Ronnie Anne try to cheer her up after the loss of her pet frog. They tell her about Dia de los Muertos, but accidentally convince her that her frog will physically return from the dead. They later try to convince Adelaide that Froggy returned by using a fake. But then Adelaide assumes she can bring anyone back from the dead and tries to bring back her great-aunt, Abraham Lincoln, and someone named Mr. Woodford. Sid, Ronnie Anne, and Carlos try to keep the charade up, but Adelaide eventually finds out. She calls them liars and locks herself in her room to get away from them. Later, Rosa explains to Adelaide what Day of the Dead is really about, this made Adelaide feel better.

Sid convinces the pet store guy to let Adelaide keep the frog and Adelaide is happy to have a new friend.

In "How to Train Your Carl", Adelaide goes camping at the zoo with Sid, Ronnie Anne, Carl and CJ. She's the first to grow suspicious of Carl's decoy, and consistently tries to get him to respond to everything around the zoo.

In "Uptown Funk", Adelaide tries to get Carl to play with her, but when he refuses she doesn't get noticeably upset. Stanley asks her if she wanted to hang in the conductor's cabin with him, but she refuses due to having done it multiple times. When Carl suddenly grows interested in playing with her (because he wants to see the conductor's cabin) she's initially suspicious, but she happily goes along with it. Throughout the day, Adelaide plays all her favourite games with Carl; tea party, princesses, and her version of El Falcón de Fuego, putting him a little out of his comfort zone. She then has Carl pretend to be a married couple with her and takes him on the train. During the train ride she realizes Carl was just using her to get into the conductor's cabin and is very cross with Carl.

When Stanley confronts Carl, Adelaide apologizes on Carl's behalf. In the end, Carl and Adelaide have a superhero tea party together, now really being friends.
