Mine cases: fill out the Skyblock!

There is a flying Skyblock island in front of you. Now it has a regular chest and a bunch of free blocks. Fill the island!
🗝️ Open the chests and get new mobs! Each mob has its own level of rarity - blue, purple, red, gold. The higher the rarity, the harder it is to get it, but the higher its cost! 🗝️
💰 Sell mobs or leave them to live on the island! They can jump funny and make unique sounds! 🎵
🎨Arrange the mobs as you like, create funny combinations - create an island of chickens or an island of creepers! 🤪🤓
🎁 Buy new chests with other mobs! What is inside the Secret chest? 🎁
🏆 Will you be able to collect the entire collection and fill out the Skyblock? 🏆
