Tails' real name is Miles Prower. Sonic gave him the nickname Tails for obvious reasons, but also because of the fox's immense dislike of his given name.
This episode is number 20 in production order.
This is one of the only two episodes that Tails' proper name (Miles) is used.
The music is at a slower pitch (including the Sonic Says segment) compared to the other episodes.
When Sonic is flying on Grounder, he says that it's a cheap flight. This was probably referenced in the intro cutscene of the hero story in Sonic Adventure 2.
