How do I prove the baby is innocent?

Question

I found Wildberry Princess' Diary and delivered the dessert pizza to get the Receipt, so I can prove two of the three people Lemongrab has taken are innocent. But Peppermint Butler won't sign anything proving their innocence until I can prove all three are innocent.

How do I prove the baby is innocent?

Answer 1

You have to talk of the Duke of Nuts, his youngest son, Second Nut Son is missing.

He'll provide you with a copy of his Birth Certificate for identification purposes, you can use that as evidence to prove that the baby is in fact a baby.
