Whoops, skipped part of the Arctic! Charlie was exploring a polar bear den, very dangerous as we could hear the bear snoring and occasionally the noise would get too loud and he'd wake up & roar!

He was having fun doing his own thing.  He'd surface once in a while, then go back under and stay for a while. "I am the walrus, Koo Koo Ka Choob!"

Of course you had to visit Antarctica also!
