It might not be an EXACT Little Strongheart, but it was certainly easier than making a whole new body, head and face flexes. Also, the model might be a bit clumped up if you use the stand tool in Garry’s Mod; this can be fixed by just clicking on her midsection.
EDIT: Tweaked a body a LITTLE bit. It’s not that much of a difference, but it’s a little less ‘round’ than in the picture.
