Harry the Hawker is a character that appears in the Adventures of Sonic the Hedgehog television series. He is a seller of souvenirs related to Sonic, even if a lot of them are forgeries, such as "gum chewed by Sonic" despite the fact Sonic claimed to not actually chew gum.
Harry even went so far as to sneak into Sonic's hotel room and steal his Hi-tops in hopes to chop them up and sell the pieces as souvenirs. Sonic had him arrested. Even though things didn't end well between Sonic and Harry, he still attended Sonic's birthday party.
Initially, Harry was a greedy and dishonest person. It is possible that he has had a change of heart after he attended Sonic's birthday party.
