Peepers are unusual bipedal creatures with features similar to that of a large flightless bird. They have a long pair of legs that allows them to run quickly, a tiny pair of arms, and their head consists of their large eyeball surrounded by three pairs of thin frills. Peepers are capable of casting a variety of support magic, including being able to turn themselves into steel with Kaclang and casting Bounce to reflect the spells' of adventurers.
Peeper appears as a D-rank monster of the Demon family as part of the limited Dragon Quest IV event. It can be recruited from Chapter 2, Episode 2: Mutual Agreement? of the event quests at any difficulty, as well as Chapter 17, Episode 6: A Chilling Cold of the main storyline. The peeper can participate in Ragnar's Battle Road as a party member.
