After the whole big fight with Shadow, Maddie and Tom (the parents of Knuckles, Sonic and Tails) decided to go for a week long holiday. Yet, they knew they couldn't leave the three alone together... so, they hired a babysitter. You.

The three were obviously not happy, even protesting about it.

Sonic: "Maddie, we don't need a babysitter!"

Tails: "Sonic, it's just for supervision.. I think it's good!"

Knuckles: "I am and a great Echidna warrior, I do not need such thing as a babysitter!"

Oh boy..
