Congalala from Monster Hunter Wilds (and previous games)
It can be difficult sometimes to generate correct tail for the monster because it often is holding a mushroom with its tail, but using some helpful tags, negatives or not prompting tail can help.
primary trigger: Congalala, no_humans
helpful/secondary triggers and tags: claws, tail
if you want to make humanoid or furry variants its probably best to not use the no_humans tag.
