There's no challenge to begin with. Just confusion.
Confusion means that there is something inside of us that is waiting to be discovered, and for some people this can be a good thing
I watched all eight episodes of Sonic Prime and no mention of any other of the Sonic cartoons.
Only other Sonic cartoon that had a mother-figure for Dr. Eggman would be Mombot from Sonic Boom.
I see, I only have time to watch four episodes so far, four more to go.
I forgot about Mombot. For a guy who hates Sonic Boom, somehow you managed to remember the show better than me.
