I'm just pitching a few ideas for things the toy vendors could sell.
The gnome cubimal is pretty self explanatory- a cubimal that looks like a gnome.
The magic 8-ball could be shaken to answer simple yes/no/maybe questions.
The Jack-in-the-box would be a little box that you crank and a random puppet jumps out and causes a random effect: high-jumper, smashed, no-no, purple, crab mind, or any other buff/debuff ordinarily obtainable in-game.
Feel free to use this thread for your own toy ideas, too. When it comes to toys, the more the merrier!
