The Small Cute Animal

Some little animal (most likely mammalian) hangs out with Hero or their girl friend and is commonly there Just For Show. But don't judge a book by its large, cute, shiny, subtly creepy eyes.

Examples of Small Cute Animals
Tenga Toppa Gurren Laggan - Boota: The pig-moleundefined Simon (pron. See-Moan) owns. He does little and really only exists for comic relief. Definitely there Just For Show. He also had his hand at diddling around in Boo-Beez a few times!

Pokémon - Pikachu: This little electric mouseundefined certainly isn't here Just For Show. As Ash Ketchum's closest companion for many, many years, Pikachu has surely earned its rights to be The Mascot for Pokémon.

Spyro - Sparx: Spiro's small Flying Guide friend. Even though he doesn't fight, Sparx acts as Spyro's Health Meter by changing colors and a guard as without a dragonfly, young dragons like Spyro would be much more vulnerable to danger, even to the point of being killed in a single hit.

Naruto Shippuden - Tonton: Named that because she weighs a ton (ton)''. ''No?undefined

The pet pig Shizune and/or Tsunade own(s). She's even got a little shirt on, but unfortunately also happens to be a Pantsless Animal. Right along with Boota, she's only for comic relief. There might be a little trend going on...
