These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: While not quite up to the level of his SatAM self, Robotnik once tricked Manic with a robot made like a baby hedgehog in the hopes that he'd get attached to it...and reveal where Sanctuary, a place of refuge for children and infants was. So he could destroy it.
Another time, when confronted by a Chaos Emerald-fueled Dingo that was poised to destroy the planet, Robotnik was willing to let it happen if it meant the hedgehogs would die with it.
Ho Yay: At the end of the second episode, Sonia kisses Sonic on the cheek for a job well done, and Sonic turns to Manic and says, "You're not gonna kiss me, are you?" Manic's answer? "No way, but you are kinda cute." One of the funniest lines on the show.
In another episode, Sonic asks for a dance while looking Sonia's direction. She accepts, but then he says he was talking to Manic, and the two begin slow dancing. The pair had a surprising amount of this.
Uncanny Valley: Some of the characters in this show really crawl close to this territory. (i.e. Just look at Sonia's adoptive mother in the first episode-she looks like something pulled out of a Renaissance Fair!)
