Rubber Kin

Rubber Kin attempt to launch themselves at the player. They deal no contact damage, and simply knock the player back. However, they can knock the player into other enemies or into pits. If a Rubber Kin is Jammed, they will deal one heart of damage upon contact with the player.

While Rubber Kin are in flight, they can cross tables and pits. Being shot or striking another creature stops them.

Trivia

 * Rubber Kin are a reference to rubber bullets, a non-lethal type of bullet that tends to bounce uncontrollably.

Tazie
Tazies behave like Rubber Kin, but predict the player's movements and deal damage if they successfully ram into the player. They will not deal damage if they are not charging. Despite appearances, their attack deals contact damage, not electrical damage.

Trivia

 * The name Tazie is a reference to the Taser, a brand of electrical weapon that disrupts muscle control.
