The insomniac Pumbaa makes Timon read him warthog/meerkat versions of The Ant and the Grasshopper and Goldilocks and the Three Bears. Timon dislikes every story he reads, so he makes one up.
"Wide Awake in Wonderland" begins by introducing Timon, a meerkat, and his warthog friend, Pumbaa.
At the start of the episode, Pumbaa wakes Timon up to tell him a bedtime story. Timon makes up a quick story so that he can go back to sleep, but Pumbaa wants his friend to read him a real story. The warthog gives Timon a big book about meerkats and warthogs.
Timon starts reading a meerkat and warthog version of "The Ant and the Grasshopper," with the main characters being a hard-working warthog and a happy-go-lucky meerkat.
In the story, Happy-go-Lucky Meerkat makes his day by dancing while Hard-working Warthog works. He asks Hard-working Warthog if he could join him, but the warthog says that he's too busy and that he has to work before the cold winter.
Then Happy-go-Lucky Meerkat lies down eating some bees, while Hard-working Warthog takes out some bugs on leaves and puts them in his basket. When the cold winter comes, Hard-working Warthog is in the cabin enjoying his meal while Happy-go-Lucky Meerkat is outside in the snow freezing and starving to death.
Timon dislikes the story and Pumbaa wants him to read another one. Timon then reads a meerkat and warthog version a of "Goldilocks and the Three Bears," with "Goldi-Meerkat-locks and the Three Warthogs."
In the story, Goldi-Meerkat-locks peeks through the window of a house to see if there is anybody home. He sees that there's no one and breaks in. Goldi-Meerkat-locks eats all of the warthog's food and then takes a nap. Then, the three warthogs get in their house and see that there is a home invasion. The baby warthog sees Goldi-Meerkat-locks and then the meerkat gets arrested by the Vulture Police.
Timon dislikes this story as well, but Pumbaa wants him to read another story. Timon looks for a good story in the book, but it turns out that every story has warthogs in a good light and meerkats in a bad light. So Timon decides to make up a story about a meerkat named King Timin.
In the story, King Timin gets well-treated by a sun and a moon. Then, a warthog dragon appears and the king kills it with a toothpick. Then, King Timin defeats other kinds of warthogs, such as a grandma impersonating warthog, a mean old warthog "Rumpled-wart-skin", a warthog witch, a warthog genie, and a giant warthog from the beanstalk.
After Timon concludes his story, he sees that Pumbaa has been sleeping throughout his story, much to the meerkat's anger.
