Wow, the amount of different animations/actions is quite amazing, and imo you nailed all of them. Can’t wait to see them with added particle effects 
Though, I think the ‘idle’ & ‘ambient’ animation should reflect the bouncy and unstable personality of the creature, meaning that the creature should appear a bit “hyperactive” and to a certain extend nervous.
E.g. by:
- Speeding up the ambient animation a bit.
- Letting the creature shift from one foot to another in the idle animation
- Adding occasional small twitches.
Can´t wait to relive my days as “Squig herder” from Warhamer Online 
PS: Will this creature always explode in the same way or will there be different kinds of explosions ?
