❓ FAQ
Is the Summer Index still available?

What is Sushi Inu and Girafini Raftini?
These two brainrots appear in the official Summer Index but their data (rarity, cost, income) is not yet confirmed in our database. They may be new additions — check the full brainrots list for the latest data.
Can Rocketini Frostini and Frullato Framingo still be obtained?
Yes — the codes that gave them (SUMMERUPD3) are expired, but both still spawn on the Red Carpet. Rocketini Frostini ($700M) and Frullato Framingo ($3B) are obtainable through normal gameplay.
