- Concise description
Disguise. (50 minutes.) You look like a Grentch.
- Following /sit with /stand will cause you to fall backwards. This will also repeatedly happen while remaining in /sit as an idle animation.
- There are two different running animations in this form. One is a loping gait, with more arm swinging and wider steps; the other has shorter arm swinging and shorter strides.
- This disguise is received by using a Mischievous Tonic, an Everlasting Mischievous Tonic or a Mysterious Tonic (random effect).
