Pooh's skill is a little different than others. When you trigger his skill it stops the timer for 4-5 seconds (depending on skill level). While the timer is stopped you can connect chains of Tsums and when the timer starts up again all the chained Tsums count as one big chain. Also, to make it even better it is much easier to create chains during the stopped time. While it is nice to have chains of Tsums ready to go when you use his skill it normally isn't really neccessary as a bunch of smaller chains are just as good as a few big ones. You can actually get a good number of coins using Bumblebee Pooh you just have to be quick while the timer is stopped and as with a lot of the Tsums the more you use Pooh the better you get with his skill. One strange thing about Pooh is that he only has 3 skill levels despite being a Premium character. This is probably because when he was released in the Japanese version of the game there was actually a whole event to get him and he wasn't just available in the premium box like he is now.
