Ding-A-Lings are small bell-like creatures and members of the Smithy Gang.
Mario and his allies encountered the Ding-A-Lings in Smithy's Factory. They, along with their ally Count Down, guarded an early part of the factory. Mario and his friends attacked Count Down and during battle it became obvious that Count Down was merely a powerful puppet used by the Ding-A-Lings. Mario and co. managed to defeat the giant clock and its masters and move on to the rest of the factory.
Ding-A-Ling can attack physically or use special moves, such as Dark Star, which is similar to the special attack used by Mallow, but targets a single character for high damage, Doom Reverb, which casts Silence against a single character and Fear Roulette, which KOs a party member at random.
