I still regularly think about the old Sonic the Hedgehog cartoon. The more anime one with an overarching storyline, not the episodic Looney Tunes kinda one (though I did also like that one for the comedy). I haven’t watched it in years. I’m not sure how to find it, either. Did it have a subtitle or something? It was the one with Sally Acorn, Bunny Rabbot, and Boomer. I only remember those characters in that specific show so hopefully that narrows it down.
