I am now 28 years old and there was a show that I used to watch as a kid on Nick Jr. It was about the same time as Pin Wheel, and eureekas castle. It was about a shop hat people ran and they had a puppet mouse that would come to life and hide from certain people, but would come out for other certain people. I remember vaigly. It has been a long time since I seen it but it was like a toy shop or something. Can anyone help me?:confused:

Sounds like it might be "Today's Special".
