Hardy is an alternate version of Squirt. It charges at the player until it runs into a wall or obstacle. Upon impacting a wall or obstacle (besides gaps), 8 rock projectiles are fired in all directions. On the second and third impact, Hardies will additionally shoot a chaotic cluster of stone projectiles in the direction they were charging. After three impacts, Hardies will break themselves open, causing rocks to fall from the ceiling, some of which may be Rock Spiders. Hardies spawn a Dip upon death. If a Hardy impacts a rock or a door, those obstacles will break open.
