Enzo (エンツィオ, Entsio) is Dino's pet snapping turtle that expands when it absorbs water. During Dino's training with Reborn, Dino asked for Leon as a result of succeeding in his training, but, instead, Leon gave "birth" to Enzo and Dino's bullwhip. According to Dino, Enzo's biggest size is enough to crush a house. Enzo's size and aggressiveness increase depending on the amount of water it absorbs.
