Giant Shelly

Giant Shelly is a snail enemy found in the underground layer. When the player approaches it, it will attempt to inflict damage by jumping towards them and then rolling along the ground. While rolling, the Shelly can move up 1-block inclines but will be stopped by a 2-block wall. Jumping over a rolling Shelly is an effective defense, but tunnels with low ceilings can make this a dangerous foe in the early game.
