Hrm. Obviously a Monster Hunter reference. 上手に焼けました "Well cooked," except the verb is changed. Dictionary tells me 剥ける means "to peel off; to come off; to be taken off," presumably referring both to her self-satisfaction at peeling the banana, and to the condition of her top.
ムケる might also be some other verb entirely, I don't know, but the above sounds plausible. I, however, can't come up with a good way to express this in English.
I also have no idea what that thing in her right hand is. It bothers me.
