Kayanba has a felyne type of mask as well. I posted the crystal jhen fight with Bracchidios hammer down below.

Yow can see that he throws multiple bombs at the monster during the second phase of the jhen fight.

So I may be wrong but looks like cha cha has both felyne and melynx and Kayanba has a felyne kind of mask.

I think all three masks throw bombs at different levels.
