A few Pufflings
Pufflings are smaller sub-species of Popples owned by Mike and Penny who appear exclusively in Season 2. There are 6 of them that are a different color: Red, Blue, Purple, Yellow, White and Magenta. They communicate by making high-pitched warbling noises. They usually reveal a riddle on a piece of paper (or a tag on the toy) when turned inside out. There are 24 riddles associated with the Puffling toys.
