This is topical reference both recent enough and highly publicized and joked about enough that there's a good chance older kids actually will get this one, but it's still insider-y enough (not to mention hilarious enough) to put on this list of things adults are most likely to fully appreciate. Yes, that horrifying, tooth-filled original design for Sonic in the "Sonic the Hedgehog" is back in "Chip 'n Dale: Rescue Rangers," voiced by Tim Robinson from "I Think You Should Leave."
"Ugly Sonic," as he calls himself in the film, a distinct character from the normal Sonic — where normal Sonic "gotta go fast," Ugly Sonic "gotta go slow." Unlike so many other characters who appear as brief cameos, Ugly Sonic actually plays a significant role in the film's story, showing up at two different pop culture convention scenes and eventually helping save the day alongside the FBI. "Chip 'n Dale: Rescue Rangers" may be making fun of the horrible artistic decision-making that led to the original Ugly Sonic design to begin with, but it also oddly gives the most respect this frightening rodent has ever received.
