Huh; big enough that you do kinda want to block it makes that ability a lot more relevant than it (bushido, rampage, etc.) usually is.

Seems solid.

Seems rather weak when compared to a card like Baloth Gorger, though.

the "by non-Theropods" (note capitalization of subtypes, btw) seems unnecessary. Being "just" a 5/3 for four in green probably doesn't need a drawback beyond "only when blocked" - though I can't be sure there is no method to this.

Also, "hangry" tops the list of words to put into your flavor text to break immersion. I tried "fidget spinner" and it sounds more like something that actually belongs into a Magic setting.
