When Somna was announced my friends and I were trying to figure out a theme. First I thought, oh if it's a dream theme, then we could be counting sheep, or hug plushies.
Somehow that evolved into numbered, collectable plushies.
I made 8 retextures of Spaghet's cute kangaroo pooltoy avatar, but substituted the pooltoy nozzles and handles for a little zipper and tag.
I had some fun with the idea of a collectable toy. Basically, I'd swap through them randomly during the event and allow friends to clone them. Then, to collect them all, they may have to trade with their friends and so on.
