Hi it's been a bit, decided to upload an edit of primarily the wererabbit transformation, that makes a few changes to the sequence itself. I'll quickly breakdown some of the changes and the thinking behind it.
1. 0:05 when wallace says 'vegetables' like that after he grows bunny teeth, as he's now entered the very outset of the transformation, I'd figure he'd enter that bunny state of mind, meaning there'd only be one thing on the mind.
2. 0:16 an additional sound effect to highlight more of the transformation, with wallace reacting to himself enlarging between shots.
3. 0:20 this one's more complex, when the bunny tail pops out, I'd figure now since wallace as a bunny nose, he'd instinctively sniff the cottontail, leading to his reaction.
4. 0:27 given I changed the tail part, I moved up the o face reaction to his bunny leg transformation. I'd imagine in reality he'd have started to have more fur on his face, though I think the fluffier ears help to mask it a bit. After this there are a few more sound effects from wallace as he transforms offscreen.
5. 0:38 more reaction sounds from wallace as he enters the final phases of his transformation.
6. 1:08 this is unrelated to the transformation, but I wanted to add this anyway, where in-between shots of him thinking he sees a carrot, wallace does some more wererabbit-y sounds like licking and chewing his lips.
