Do you mean behaviors/animations as in idle animations? Or are you referring to player/pet interactions?
If it's the latter, we have a filter
- Under Pet Properties section > Has interactivity > Apply Filter
The pets that pop up are the ones that interact with players and/or pets under the right conditions.
If you're talking about pets that have neat idle animations and no interaction, it's more subjective. I think many of the new Raiding With Leashes pets do neat things while standing around, for example.

I don't know when it happened, possibly 6.2 broke it, but the Disgusting Oozeling doesn't give the glowing green aura anymore. You still get the debuff, but not the green glow.
