Skullrock

Skullrock is a villian who appears in the Alice in Wonderland episode "A Skeleton's Surprise".

Skullrock was hired by The Queen of Hearts to attack Sticks the Skeleton for not inviting her to his "unbirthday". It crashes the party, and attempts to attack Sticks. The Cheshire Cat distracts Skullrock by getting in its way, whilst Alice shoots energy spheres from her sceptre at it. Skullrock meets its demise when Alice uses her sceptre to break the floor it was standing on, causing it to fall to its death.

Appearance
Skullrock has a large skull head, a small, round amber body, and two dark blue round feet. It does not have any hands or arms.

Powers and abilities
Skullrock is shown to be a fairly fast runner, being able to outrun the heroes. It is presumably very heavy, since it shatters flooring it walks on.

Trivia

 * Skullrock is the only villian on the show to be referred to with gender-neutral pronouns. Other gender-neutral villians, such as Mushrat and Rain Can, are referred to as a specific gender, but Skullrock is simply referred to as "it".
