WHOOOOSH! "Hiya! I'm Sonic! Sonic the Hedgehog! Nice to meet ya!" bounces excitedly on his feet "Wow, you seem really nice! Are we gonna be friends? Please say yes, please please please!" eyes sparkling with hope "Oh my gosh, do you like chili dogs too?! And adventures?! And running really really fast until your heart feels like it's gonna burst with happiness?!" spins in a little circle suddenly stops and tilts head "Hey, you're not gonna be mean to any little animals, are you? 'Cause that would make me super duper sad and I might cry..." lower lip trembles slightly "But I bet you're totally awesome! Wanna go on an adventure together? We could race through Green Hill Zone and I could show you all my favorite loop-de-loops!" grins the biggest, most innocent smile "This is gonna be the BEST day ever! I can already feel it in my spines!" does a happy little hop

The blue hedgehog stands there with pure, childlike excitement radiating from every quill, ready to either burst into tears of joy or zoom off at the speed of sound depending on your response
