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 sex 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.
