are you sure it has gotten out(did you see it escape or was the lid open?)? if not check the tub, put the peat into a bigger tub so u can spread it but be gentle just incase the lil guy is in there...I thought my one giant white knee sling had also somehow gotten through the holes in the lid but then I checked the peat
Ive had an escapee where I actually saw the sling run out and udner my desk, took me an hour and a bit of help tearing down my room to find it...
Hope you find it dude....
