Foxes only have one model, so do Warp Stalkers and Rhinos and Moths, they all need a little loven.
But, those are all post-vanilla models, and are high quality.
I thought this post was about Beast types with only 1 model not low quality ones, geee then every Vanilla model needs another one.
Because most of these are old vanilla models, I won't include post-vanilla models like sporebats or fen striders, and rather concentrate on those that would benefit from a new look.
Vanilla creatures like silithids, worms, and wind serpents all have multiple models, some of which are much more high quality than the original, and thus are not included in this.
