Such a sweet little man with such a great surprise in store -- a new happy, healthy home! What a change this must be for him. I am thankful you are there to show him a life he deserves and finally know that people are not his enemy. Bless you and all the other rescue moms and dads out there!
BTW I really love the name Peanut. There are some great Peanuts already on YT and I know we can use another.

You can even use both names. He could be Pocket Peanut -- Peanut for short. Just not one you would want to revert to initials.
