I created a Bubblegum Machine set that contains 1121 parts. In this set, there is a bubblegum machine and a candy stand.
The bubblegum machine works for real: you just have to put a coin inside the machine, turn the handle, and the surprise will fall. Inside the bubblegum machine, there are 10 balls in which there are surprises that will allow you to build a candy seller, but you will be able to change the surprises and put whatever you wish inside the balls.
The candy stand is well provided with candies, cotton candies, drinks, and a tiny bubblegum machine.
