@HolloNut ahh, at one point in my deduction i had them all right. i switched Ludwig from 4 to 8 and shuffled some around because #4 was so steamy and huffy and i thought the little clouds were a clue pointing to Larry since he also had them in his portrait
@HolloNut After staring at this for longer than I care to admit my best guess is:
Iggy: E1
Lemmy: G7
Ludwig: A8
Morton: H2
Roy: C5
Jr.: F3
Bowser: B6
Larry: D4
