Updated list. If anyone is interested I will be happy to swap the koala for a purrer. I've decided my engy needs two cats and one should be orange.
 
Decide to crack my last two fall crates in the hope of getting the medic mask. Got it and a Track Terroriser. The latter is up for sale.
 
I can't sell more than 3 but if that's OK then add me. I'm keeping the rest to use although it would help if I could find a team who don't give up at the first problem.
 
Traded koala and bushman for engineers 2nd cat. Painted him orange and going to name him Ginger Tomkins.
