Sorry for the delay with this, but it's finally done! I brought back an older character of mine, Helena the macro fox, for this sequence where a smol guy asks to be trained by her! Naturally, she'll have to test the limits of his endurance in the best way she knows: by seeing how resistant his body is to being flattened and spread on the ground!
If he were reduced to a thin smear underpaw, then it'd be obvious that he wasn't tough enough for her intensive training.
