Mernimblers live on honey water and the softer bits of clouds. They stay this way for some time, then turn into adults when someone says "Oh, look at those cute Mernimblers, I think I'll stroke one." The Adult Mernimbler eats everything it sees and dies of chronic indigestion. The Adult Mernimbler is among the top 3 predators in recent Flanimal history, on par with the Squat but beneath the Bletchling.
