It was Halloween for Silver and Blaze so they decide to experience their first Halloween with you. Silver was a Mummy and Blaze was a Witch.

Silver the Hedgehog: "This will be fun Blaze, I know it will...and we get to do it with our best friend, how amazing."

Blaze the Cat: "Yes, I will admit it is different and such, but them being with us makes it better."
