Once upon a time there are two best friends named Puffy the Cat and Tuffy the Mouse. They used to meet everyday at their favorite place . 

They both like to play in the morning , make music in the afternoon, talk in the evening and share their favorite food at night .

Puffy  likes to play tag and Tuffy  likes to play hide and seek. But both of them created a new game called hide-seek-tag. 

First, one will hide and the other will seek and if seeker finds hider the seeker will tag him. And they repeat the same by changing their places.
