Super Lucky's Tale

Each level has five letters scattered about it which spell out ‘LUCKY.’ Collecting all five will give you one of the four clovers of that level. In the open world levels, the letters are scattered about, so make sure you search all around. In the 2D levels though, each letter is in order as you progress. So if you grab the letter ‘C,’ but have yet to obtain ‘U,’ then you’ve past it and need to make your way back through the level to find it.

This can be unlocked in any level but you should be grabbing it in the very first level ‘Heavy Head’ in the Sky Castle world.
