I would be disappointed if the Croakers (cool name, BTW) didn't have some sort of tongue grappling / disarming / tripping ability.
Lots of good ideas on this thread.
Thing is, if I were introducing a kid to 3.x, I think I would steer them away from the grappling rules.
honestly, the best bet here might be a refluff of Pathfinder's throwing net.
