Frog Mesh Won't Stop Bouncing

I'm trying to replace the meshes/textures of all the collectable frogs, but I'm running into a particle animation problem. I understand the VFX and I've turned it off in the object tuning, but that only covers the tongue and eye animations. The problem is with a seemingly unmentioned VFX animation that makes the frogs' necks inflate. The object definition and LODs all point to a particle animation, but I'm unable to figure out how to turn that off in Blender or otherwise. I've tried switching out the rig and mesh with no "FX_creature" bone to negate the animation, along with a few other surface-level fixes I thought to try, but nothing is working. When replacing the mesh with my own, the entire object bounces up and down with the frog neck animation in game. 

I'm thinking the solution is replacing the entire .blend file with my own to exclude whatever "particle animation" is built into the original frog mesh, but I don't even know if the animation I want to get rid of is in the .blend file, object definition, or a VFX resource I'm going to have to dig up. Can someone help me figure out how to get rid of the throat bouncing animation on the frog? I've never run into an unmentioned object animation like this before.

Here's the default frog object, with the only difference being the eye/tongue VFX turned off in tuning. Everything else is untouched:
