ahhhhhhhhhhh. the key frames are the issue.
well, the solution is to delete the key frames causing issue. but deleting key frames counts for all bones movements in that key frame. which is usually alot.
a work around that is to go into the selection mode, select the glitchy bone, then select the key frame that gltichy bone is glitching in, and delete that bones glitchy frames.
because if you start deleting entire key frames you'll find all kinds of other bones breaking too, as they too use that key frame.
but if you select nothing except the bone your trying to fix/edit, then you can ''delete'' its ''glitchy key frame'' without deleting the entire key frame. or altering the animation at all.
so you don't want him bobing up and down so much? during stand alternate and stand work alternate? [stand alternate work is not a real animation name, work comes before alternate always]
first, go to the animation tab, and choose the animation you wish to alter first, in this case, its Stand Alternate
secondly you go to the ''movement'' tab (f3)
then select the glitchy bone, in this case its ''Bone_Box2'' because its the root of the model, and the source of the lifting and dropping.
then press ''M'' which will give you a slightly different window. for ''movement''
but instead of moving Bone_Box2 anywhere, or doing any thing with it at all really, we only press ''M'' to show a special check mark box called ''Highlight Key Frames'' (Highlight KF) check mark this box.
once its checked, and Bone_Box2 is the only thing high lighted, and your inside your very specifically chosen animation (stand alternate) you'll notice a lot of key frames in ur animation have ''vanished'' this is because they cannot be seen or edited when only one bone is selected, this is how you see a specific bones specific key frame animations.
now simply press right click in the keyframes bar, select ''clear'' and now Bone_Box2 will have no key frames inside it. he no longer bobs up and down at all. but only for that animation, leaving all the other animations intact.
wash rinse repeat for stand work alternate and your done!

I have done this for you, I also tried to wiggle the fingers for stand work alternate some more, but Figured you'd rather do that your self, so, here you go.
Edit: I also used whats called the ''Scaler'' to make your burrow splat hole model, shrink and grow during morph and morph alternate. something not included for crypt fiends but is seen on the scorpions and beetles.
