A Carroboscis is a strange carrot-like creature that can hover in the air. These monstrous vegetables reside in Booster Pass, the entryway to Booster Tower. Although fairly strong, Carroboscis only aid other monsters, such as the Spikester, in battle; Carroboscis never fight on their own or with their own kind. In a fight, a Carroboscis will jump towards the opponent and flash its frightening green eyes, causing damage. A Carroboscis can also summon magical bells to attack intruders with musical spells while using Doom Reverb, Spore Chimes, and S'crow Bell. These musical magic techniques will cause adverse status ailments, including the Silence, Scarecrow, and Mushroom status impairments.
