*Noob here* split body/fillet doesn't quite work not sure why

I have a 3D model I found on CULT3D and I'm trying to remove the limbs and tail. I got the tail and legs but the arms can't be generated into face groups then deleted off like I did to the other limbs. I've tried split body and fillet tool to no success. I converted into solid from mesh.

Like the title says I'm very new (to this CAD stuff) thank in advance!

Can you Attach the original stl file here?

How do you want it split?  The body splitting tool must completely intersect the body.  I split it down the middle as an example.  Model is attached.

I would probably do this in the Mesh environment.  Trying to do this in a BRep will leave big planar areas of your model that won't look right.  The basic idea is:

  1. select and delete mesh facets from the arms
  2. use either Repair or Erase and Fill to close the holes
  3. then, convert to BRep

if you share the original mesh, I or someone else can show you how

I’m on my iPhone right now I won’t be able to edit/play around for a few hours. I appreciate everyone’s replies. This is the one is in edited.

The video below illustrates a few techniques.  It also illustrates how painstaking this process can be (I apologize for the length here...).  Better mesh users can probably do this much faster.  But, the basic idea is:  Select all the facets of the arm, and delete them.  Lots of selection tricks here - Expand/Shrink, using window select vs freeform selection, etc.  Take your time, delete a bit at a time.  Then, the real trick is:  if you have an opening in your mesh, select one facet, then go over an adjacent facet and do "shift-double click".  This will select the hole boundary.  Once that is selected, use Erase and Fill to patch the hole.  Play with the density until you get about the density you are after.  Repeat for the other arm...

I took off all the arms, legs, and tail.  It would be better for you to learn to do it, but, in case you need a reference mesh, here is what I was able to do with the techniques I described in the video.

How did he do that at 3:38? What was the command? 
thank you guys a ton, now I need to think of more projects. If anyone has beginner project ideas let me know!

if anyone was wondering I plan to make this as a cake pop mold for my friend and her daughter haha

That was what I said in the post was "the real trick" in this method.  It is totally non-discoverable, I admit.  What you do is:

  1. with "Face selection" enabled in the Mesh palette, select just one mesh face/facet:

  2. move the cursor over an adjacent face and double-click, while holding down Shift:

  3. this will select a region around an open hole:

Here is a shorter video.  It doesn't really capture the Shift-double-click, but that is the trick:

I skimmed right over that, I'm sorry to make you repeat yourself. When I go through the filters (I'm not sure how to open the fillet) I've selected face mesh and it selects the whole body
