Posey

"POSEY" is a possum that first appears in Sonic In Your Face, on the third story. She meets Tails at a Sonic-Con, and is the resident Sonic expert, there. Tails is instantly smitten with her and she's intrigued during the fake story of Tails' speech at the con. When Robotnik crashes the party, Tails outsmarts Robotnik and sends him away. He is rewarded with a kiss by Posey, and they head back to the con, while Tails point out to Posey that he has "more things in his speech that he needs to discuss with her".
