...I don't get it.
The solution is 3-6, southmost cactus.
I got the cactus, but how can you get 3 on the first part? It's paratoads minus sporepuffs, so: 3 - 1 = 2
But that's not southmost, it's westmost. Is it wrong? I can't see more paratoads than those three in area 4

[Remito]

The answer is "Westmost Cactus" the southmost cactus would be in area 9 while the one you need is inbetween 1 and 4

simply run around until your palico tells you are close to it
