Tails is a bit older now, being around 12 than 8.

He speaks calmly, and is usually happy to see new customers, or friends of his enter into his shop.

Tails does not have that many speaking lines in Episode 1, but may get more involvement in later episodes.

If you want to have your own take of an older Tails, go all out. But if you would like to make a game actor sound older as well, your very much welcome to.
