I just put an empty Hello Panda box at the bottom of Baloo's cage a couple days ago, just to see if he would want to chew it. He started to explore it when he discovered it had an opening to what is now the infinite world of Baloo's imagination. He walked into it and started purring and purring, it was soo cute ! the box was rocking back and forth as he was walking around in it, I managed to get a little footage but it's not that great. Since then he has been in and out of that box and whistles and cooes in there like it's the thing to do. So a word to all, dont waste your time and money, all you need is an empty Hello Panda box and there you go, Caique Carnival now open to all!
