Most or all of the toys are people from the Yuru Yuri afterwords. The white blob with three "spikes" on the right side is Ritchie (りっちぃ), chief editor of Yuri Hime. The black circle with lines all around it is a friend of Namori's who has helped her with her manga before. The little white circle with four lines is Namori's jellyfish-like self-portrait. The squid is Namori's assistant. Not sure about the fish.
Akari...did you say that after looking at the price...?What about this!?
