Munchlax is a bit different to every other Honey Tree Pokemon. There are only four Honey Trees in the game where you can find Munchlax, which are random of every player. It will only be a 1% Chance of getting a Munchlax on one of the Munchlax Honey Trees, being between the levels of 5-15. Munchlax is the pre-evolution of Snorlax. The location of the Munchlax Honey Tree depends on the Trainer ID and Secret ID of the player; I shall put a hyperlink to Bulbapedia for more information on Munchlax Honey Trees.
