Drakey

Drakey (キラドー, Kiradō) is a bat-like animal. It is suddenly killed by Hero while the protagonist is talking to Dolottle for the first time.

Characteristics
Drakey is an egg-shaped pink bat, with stick antennae that have rounded ends, and bat wings roughly the same size as it's body. It has a simple face with beady yellow eyes and two large fangs protruding from it's mouth.

Hint
Drakey followed Slyme closely behind in death, but the little guy is a bit nocturnal.

Trivia

 * Like Slyme, Drakey is a direct reference to one of Dragon Quest's monsters, Dracky. Though the English translation simply spells the name different to make this reference, Drakey's Japanese name is "Kiradō", which is "Dorakī", (Dragon Quest's Dracky's Japanese name) phonetically reversed. DQ's Dracky is a common, weak enemy just like Slime, which makes it entirely fitting their Moon counterparts would be the first animals the protagonist may save.
 * On the original official website for Moon made in 1998, Drakey's flavor text was the following: "コウモリの一種で夜行性. ちょっとハデめのピンクの姿はみんなから愛される‥はずなのに‥勇者はまっぷたつ. ", which translates to, "A nocturnal bat. With such a stand-out pink appearance, it should, without a doubt.. be loved by everyone, but.. the hero slices it in half."
