In Aniimo, the Legendary Cheerful Blind Box comes from the Season Shop, not a crafting recipe or quest drop. It has one function: open it to receive a random reward. The prompt encourages you to shake the box and try to figure out what’s inside.
Quick answer: Claim the Cheerful Blind Box as a weekly benefit from the Season Shop, then open it from your bag to collect a random reward.

How to get Cheerful Blind Boxes in Aniimo
The Cheerful Blind Box comes from the Season Shop as a weekly benefit. That means it refreshes on a weekly cycle rather than being a one-time pickup, so you can collect it again each new week the benefit is available. There is no material cost or crafting step involved. Head to the Season Shop, claim the box, and it lands in your inventory.
Because it stacks up to 9,999,999, you can hold onto multiple boxes without worrying about clogging your bag, and open them whenever you want.

Opening the box delivers a random reward. There is no fixed prize list to plan around, so the contents change each time you crack one open. You confirm it worked when the box leaves your inventory and the reward it rolled appears in the on-screen pickup notification.

If you are weighing it against the other boxes in the same family, the Cheerful Blind Box sits alongside the Epic Blind Box, which is a weekly reward from the Stamp Rush event, and the Prismatic-quality Fun Blind Box. All three follow the same idea of a sealed box you open for a surprise, so the main thing to track with the Cheerful Blind Box is that weekly Season Shop refresh.
