what if the meaning of the wish itself is malicious, so he tries to manipulate it and ends up doing good? or the wording is not ambiguous at all?
did i grow fur, or is the fur just on top of me.
In the context of what it's been marked as going well with, grow fur.
You totally have the ability to try to make the wish not twistable, or double trick the genie. That doesn't mean you'll succeed though.
Where should this comment appear?

Whenever "Wake up covered with fur" appears
Whenever "A genie appears and grants you three wishes. Each time ..." appears
