If we're referring to Frank and Dummie, they'd probably be used to seeing wacky creatures of the like throughout their travels. A tall, sentient, walking and talking carrot would probably be a first though. Maaaaayyybe would end up thinking that it's a costume at first?

Everyone else would probably be confused to hell and back about how a carrot is alive.
Bottom line is that I don't think anyone would be willingly hostile to 'em.
