I’ve seen these before! They’re produced by Bandai (the same company responsible for Tamagotchi and Digimon), and after every 100 pops, a random sound effect will play (like a dog barking or something).
They followed this with Mugen Edamame, which emulates squeezing edamame:
Then they did the Mugen Peri Peri, which simulates the action of opening boxes with tear tabs (like FedEx packages, Pocky boxes, and so on):
no but like if these kinds of actions calm you down in stressful situations tHINK ABOUT IT (the innovation not the situation LOL)
