The Levels aren't numbered since my co-creator decided not to number them. Also, the big wallet is to the right of the Home of Carock (Level 4) where you can bomb the wall. You need a key to get further into the cave to get the wallet.
For the Ladder, you need the wand fire to hit the tree far to the right in the beach area to open a Super Bomb shop. Buy a couple Super Bombs and use one infront of a cave which is blocked by a big boulder. There is an antidote shop there, buy one and then bring it to the guy who got poisoned by the snake. When you give it to him, he'll give you the Ladder. Also, remember to come back to Level 3 (the Buried Temple) with the Ladder to get another key.
Hope this helps. Another note: Atrus is going to be away for a while so I'll be taking over the quest for a bit. PM me any bugs that you find and I'll try to fix them the best I can.
