I've been excitedly waggling limbs at a Grom revamp (or spiritual successor), but had taken Whitefang's chariot laugh to mean "no", where others suggest this is positive 😅. Ahh, the wiles and whims of Whitefang reactions.
On the pot-belly front, @zamerionsuggested this is a plaguebearer carrying a book for Warhammer Underworlds who has a literal pot in it's tummy.
BUT! We do have a written response from Whitefang challenging mention of Gitmob grots being able to fit into small spaces, so we can't count out a grom gut 😁
