Fronk

Fronks are small creatures from the WarioWare series. They appear in many colors besides the most common color, yellow. The name Fronk presumably refers to both the species and the character, 9-Volt's pet Fronk. In his first appearance in WarioWare, Inc.: Mega Microgame$!, he goes by the name of Shag in the English version, which is derived from his Japanese name Shaggy. Since WarioWare: Twisted!, however, he has been known as Fronk in English, due to the word "shag" doubling as a vulgar slang term for sexual intercourse in British English.

They appear in various microgames in every installment of the series. In WarioWare: Twisted!, Fronk has his own Fronk-themed microgames that are shorter than the other games, but they appear randomly in any of the stages instead of Fronk having his own stage.

In WarioWare: D.I.Y. Showcase, Fronks appear in 18-Volt's stage, acting like enemies.

9-Volt's pet Fronk appears in WarioWare Gold. He first appears in 9-Volt's story, where he expresses concern over 9-Volt's hatred of math. Fronk, after realizing that 9-Volt has some skill in the subject, then compares math to an RPG. With this comparison, 9-Volt thanks Fronk for "kind of mak[ing] math fun", and offers to give Fronk his dessert as thanks. However, Fronk declines, saying that "an old guy like [him]" should not eat sweet foods. Fronk also appears in the ending of 5-Volt's story. Additionally, like in WarioWare: Twisted!, Fronk has his own set of microgames, which involve himself and have shorter lengths than the other microgames. However, he does not have his own stage. Instead, Fronk's microgames appear alongside others' microgames, such as in the Dancing Team and Potluck Gang stages. This game marks Fronk's first speaking role, where he is voiced by Todd Haberkorn.
