Dream Alien

Dream Alien (ドリーム星人, Dorīmu Seijin) is an alien-like animal whose body is encased in a block of ice at the Cave Guy's Cave, likely as a result of an ice spell from the Hero.

Characteristics
The Dream Alien is a teal-bodied creature, with a tail, two arms, and hands that have three-digits each. On it's head are two trapezoidal eyes with red irises, thick pink lips and a forked antenna. On it's stomach is a golden circular attachment, with round embellishments on it. In the center of this, is the teal flesh of the creature and at it's core is what could be a third red eye.

Hint
Dream alien has caused Cave Guy to suffer from a lack of sleep, and it's possible there's a way this can be averted. Perhaps yon merchant will sell thou an elixir of slumber?

Trivia

 * On the original official website for Moon made in 1998, Dream Alien's flavor text was the following: "泣き虫の子供の枕元に現れる. そしてやさしくなぐさめる‥", which translates to, "It'll appear at the bedside of a crying child, then gently comfort it.."
