Timon and Pumbaa

Timon is a meerkat living in the Pride Lands. He only appears in Kingdom Hearts II.

He grew up in the Oasis with Pumbaa and Simba, and together lived a carefree life until Nala found Simba and tried to convince him to go back to the Pride Lands with her. With the help of Sora, Donald, and Goofy, he and Pumbaa pull their courage together to help fight Scar's hyena army.

Pumbaa and Timon often say their motto Hakuna Matata, which means no worries.

Kingdom Hearts II
The Lion King (1994)

''A meerkat and one of Simba's closest pals. He found Simba, almost dead of thirst, when he was just a cub. Timon and his best buddy Pumbaa taught Simba their motto, Hakuna Matata, which means "no worries."''

And that's how Simba grew up -- with no worries, taking life one day at a time.

First Visit
On the first visit, Timon is not seen until Simba is seen in the oasis. At this point, Timon looks a little emotional to a degree, noting to Pumbaa: "Look at 'him Pumbaa, look at how he's grown. Why, when I rescued the little guy, he was only this big" and then lowers his hand to level with his knee.

He is eventually met by Sora and the gang and teach them about Hakuna Matata, which means no worries. As he leads a conga line of sorts with him at the lead and Sora, Donald, Goofy, and Pumbaa in the back, he chants "Hakuna", while the others respond "Matata". However, this carefree antic is put to a stop by Simba's fight with Nala about going back to the Pride Land.

Later, Timon helps the entire group to try and take down Scar, alongside Pumbaa. However, their attempts ultimately fail and they are cornered by Shenzi, Banzai, and Ed in a cave, which means it is Sora's responsibility to rescue them.

At the end of the First Visit, Timon is present and even delivers the line, after the gateway to the next world has been opened, "Hey! What's with the light show?", which shows other people can see the glow that is seen whenever Sora unlocks another gateway.

Second Visit
During the second visit, Timon is seen only scarcely, but ultimately helps Simba by telling him to "Live for today". He also gives some good advice before facing Groundshaker.

Appearance
Timon is a small meerkat with light tan fur over most of his body, save for the front, which has white fur. The tips of his toes, his fingers, half of his tail, and his large nose are all brown. The ridges of his ears and his "eyebrows" are dark red and his eyes are brown. He also has light brown rings around his eyes. Timon's ears point downward and he has an unexplained, short, spiky head of orange "hair" on the top of his head. His back sports several horizontal, grey stripes. Timon's forearms are unnaturally thin, particularly when compared to the size of his hands. The fur on his chest and elbows is ruffled.
