Mouse Wars!

Paul's war with the mice in the loft has reached a new level - they are fighting back and possibly even winning :-( Last night when he checked the traps in the loft, not only had they eaten the food without setting off the metal traps, but the wooden trap was missing!! How big are these mice and what are they going to do with the trap? Paul needs backup when he goes into the loft in case the mice kidnap him - which bear is going to volunteer to go with him and fight off those pesky mice?
