It's a Sokoban level with more than nine boxes. There's ten. You can count them, if you're curious.

How do we usually do Sokoban-like puzzles in Wonderland? With boxes and buttons, of course. It's the norm. It's the easiest, most obvious way to replicate the Sokoban mechanics in Wonderland, with one glaring flaw... you can't have more than nine buttons. So if we do it like that we can only have nine boxes or less.
Sometimes that's a good thing -- not everyone wants to walk around a huge level pushing piles of stuff -- but there's many great Sokoban puzzles out there which just need a few more boxes...
Back in "Just One Coin Is Easy" I have figured out that you can replace buttons with open gates. When they all snap shut, the boxes get destroyed and you use a box generator then. But in that level (and in my conversion of "Supasoka" too) the gate placement itself is incredibly obvious, you don't really need to see them visually.
How do you convert levels in which the gates are placed "wherever"? They're too hard to see when they're open, which would make it needlessly confusing. And you can't even replace the floor tiles underneath them to make the floor itself look different.
And then I figured out: why not replace all other floor tiles?

... sometimes, the best ideas are the simplest.
This is a level with the "Garden" texture, and everything else is covered with the "D" floor tile. The difference between them and the gates (which still have the default, green "A" floor tile underneath them) is incredibly visually obvious, allowing me to do a Sokoban level with 10 boxes.
The level itself is pretty simple, I don't think you will have many problems with it. Just download it to see how Sokoban levels should be done in Wonderland.
