Pellets, they are insane for pellets, it is just that simple. Thumps and Fwan are actually way worse now. This video was shot about a year ago or so, now Thumper charges Baby Fwan over and over again and she popcorn binkies over the top of him to avoid being rundown! I will have to get that on new video soon enough. But this is pretty enjoyable to watch anyway. It gets better towards the end.
