i asked a while back about this item of the adventure log. and now, after a lot of effort (well just a lot of bus rides to work) i can say that you have to make each pokemon the leader on a trip to a dungeon. i went through tiny woods over 400 times with each pokemon (it includes all individual unowns - i know because i left them to last to check) and it was so boring.

still no sign of for me though where are you munchlax - hurry up so i can finish my log.......

There is a slim chance that, when you have an apple in your toolbox and go to the square, munchlax will appear and walk through. If you talk to him and give him some food, he will give you a Munch Belt, it happened to me once.

thats what im trying to make happen ive done so much on that game, but still havent seen munchlax.........
