Some of the things we learned from the Twitter Takeover:
Tails makes gains.
Sonic has ADHD.
Shadow smells like lavender and writes poetry.
Tails has a mint addiction and has likely committed several war crimes.
Shadow and Black Doom are besties.
Eggman is a secret billionaire.
Pyjama sharks /Poroderma africanum/ -as well as some other species of catsharks (family Scyliorhinidae)- curl into a ball with their tails covering their eyes when threatened. An absolutely adorable defense mechanism!
