I don't even get why some reacted badly to that rumour?
WW hangs with animals yeah? She understands them pretty well, yeah?
Is it not possible that someone not fully up on her capabilities heard that she can communicate with a tiger, and took that as understanding that there literally is a talking tiger?
Besides even if there was a talking tiger, I think bring it on. I like Ferdinand and the gorillas that talked were pretty cool too. Also as you mention Rocket, he and Groot are my fave Marvel characters.
