Tracy makes a new mystery friend, Ben.
On the way home from school with Justine and Louise, Tracy decides to stay in the park when the others return to the Dumping ground. Another encounter with Ben leads to Tracy wanting to take him to see where she lives.
But Tracy is forced to hide Ben when Jenny refuses to allow Tracy to have any guests because of her lateness. She has to sneak him into her room, before leaving to get food. As she gets caught in the process, Tracy must try and get back to her room before Ben's found. Unfortunately Justine gives the game away and Ben is at risk of being caught. Louise has to try and save Tracy. Meanwhile, Ryan, Zac and Duke have to try and deal with a mouse lose in the kitchen.
They try mouse traps, but Jenny quickly shuts that idea down. Ryan and Zac actually catch it at last; Duke is very happy about this and wants to flatten it with a mallet, but Ryan and Zac strongly resent this idea and guilt trip Duke into just letting it go free instead.
