I have a beardie. How the FUCK do you lose a bearded dragon- they move less than a fucking tortoise on average.
They're more than happy to just sit in a nice hot spot for most of the time, unless food is in sight.
Only way Cobes could have "lost" Puff outside is if he let him out of the tank, put him outside and he ran off, which is unlikely.
Bearded dragons are cold blooded- they require heat to move around effectively. A cold dragon is a sluggish, docile dragon. It is ~40-50 degrees in Casper right now.
Still, he could have dashed off while still warm from being inside. Beardies are scared of birds, so in general they get spooked when anything is directly overhead.
A ceiling fan, or just someone moving their hand above a bearded dragon's head is enough to spook one.
Silver lining is that like most reptiles, beardies will not usually go far if they escape their tank.
Most likely, Puff is still inside, and has found a secluded spot in the bogcave to curl up and try to stay warm.
However, if Puff is outside, he is cold, lost and will not survive long.
Fuck I'm MATI. Who gave Cobes a real animal to torture when he can barely take care of himself?
That poor fucking dragon- sad, cold, helpless and alone in the Casper winter.
