The references so often made in newspapers to Exeggutor as a walking tropical rainforest appear to be nothing more than a case of an overly colorful nickname. To be sure, it is a type of tree found in the tropics, but it is not one of the towering ones which form leafy canopies and trap the clouds which make the forests rain. This nickname, however, is better understood in the context of a group of Exeggutor; its application to an individual is a wholly modern phenomenon.
Exeggutor are a highly mobile and social pokemon, and when they travel they do so in vast packs which wander great distances in search of the mixture of food and sunlight on which they thrive. They seldom stay in a single place for long, and at times their searches take them into temperate climates, although it is rare for them to survive for a prolonged period. (Their children, Exeggcute, are better at thriving in these conditions.)
A strange thing happens when they do find a place to settle. The combination of leaves and fertilizer and a strange gas they exhale which is less deadly but with a stronger greenhouse effect than carbon dioxide soon creates highly localized tropical (if not forested) climate zones, where rare or absent pokemon from the surrounding areas can thrive. It is said that a single colony of Exeggutor created the Safari Zones in Kanto, Johto, and Hoenn, all of which continue to draw large crowds to this day.
