How do I get a hamburger or a boot as my car?

These unique appearances require "fragments" in which if you fuse the required amount together (normally it's 100 or 200 fragments), will yield a permanent appearance which you can use to get the HQ appearances.

I know of two ways. Either spinning the "Lucky Treasure" wheel which costs Gold to get fragments... but this method is based on the featured HQ appearance and from past experience, hamburger and snow boot don't appear in this event much.

The other way is through the "Magic 8-ball" event where you need to use tickets to draw for either HQ appearance fragments, or permanent appearances (the latter is much more rare of course). Magic 8-ball tickets cost money though and the draws are completely random. Because it is a gamble, it can cost a lot but I believe 4 draws/tickets cost $20 each.

There is another way, sometime we have a pack that let us have appearance permanent without fuse from frag, but I can only get the ice chariot, overlord, skyfield. Idk is there any pack that let us have the best appear (boots, snowman, carousel), if anyone know pls tell me.
