From the Super Mario Wiki
Skuttler Mages appear in Super Smash Bros. for Nintendo 3DS as Smash Run enemies. As in the original game, they can summon a jet of flames if the player is in their melee range, but they can also target the player and then summon a white explosion if the player is far away. A large target on the player appears to indicate the magic explosion, but the explosion itself can be dodged if the player moves before the Skuttle Mage attacks. If players are hit by their attacks, their stats drop.
