On death Kagos delete the collision tiles they are on. Assumes that the enemy is tile aligned. This is used for those weird kago like things in Subversion that hurt on contact.

Set Properties2 (aka Speed2) to zero for default behavior, set to nonzero for new behavior.

Set the kago to have non-solid collision. You can change the enemy header so that the kagos deal more than 0 damage if you want.

Set the collision you want using room collision tiles (eg slopes or whatever). Make sure to test how the spawned bugs react to the terrain.
