On one hand, it wasn't like he'd never seen any wildlife here in the park during his runs or walks since he'd shown up. He'd not really paid any of them any attention unless it was watching the dire wolves chase around a squirrel or bird, but on the other hand... Steve had a point. He'd seen too many weird things not to question the rustling in the bushes.
Especially when said rustling turned out not to be any kind of squirrel he'd ever seen and jumped out straight at him.
Bucky went to duck out of the way, but whatever it was managed to wrap itself around his neck and tried to lick — no wait. That wasn't a lick, it was an over the top, loud kiss on the cheek. As soon as he realized what was happening, Bucky used his metal arm to forcibly pull the thing off of him, but somehow it was a lot stronger than it looked.
"Hellooooo Soldier!" It sing-songed and batted its eyes at him. Bucky was holding the thing by its neck away from him and looked over at Steve with a mix of shock and borderline horror.
