The answer was Sonic the Hedgehog, issue #224, page 5 "Dude, you're ugly and you're evil. I'm deeply concerned. Plus I've got the the sword of Acorns."
I'm looking for a word bubble that contains a misprint: one of the words a character says is printed twice in a row in a way that is grammatically incorrect (i.e. 'look at that thing thing!').
This can be in any issue of Sonic or one of the specials.
Any ideas?
