About these levels

Wild levels are not fixed. The game stores a step for each slot and adds it to a base that grows with your badge count, then adds a random 0 to 4. Those slots are shown as Base+1, Base+3 and so on. Fishing, headbutt trees, gifts and the Bug-Catching Contest are fixed and print as plain numbers.
