Detailed Walkthrough

During the event, the beautiful Demon Box Envoy, Tanya, has come to the Summer Park!

She has three kinds of Demon Boxes. You’ll just need to spend a certain amount of Sunny Coins to buy one, and then you’ll have the chance to get several times the coins you paid.

She told you that you should open the box and kill the monster in 30 seconds, or you’ll miss the reward.

You bought a box!

You can only open the box in the Summer Park or outside of Cronus City, so you went out of the city.

A monster appeared when you opened the box! Kill it!

You must kill the monster in 30 seconds. Hurry up!

So easy! The monster was dead.

You received a pack! Open it to see what's inside!

It's a Sun EXP Potion! Congratulations!

The event is so exciting! You don't want to miss it!
