Tanemon

Tanemon (タネモン)
A Bulb Digimon which has something that looks like a plant sprout burgeoning from its head. It is a Yuramon that wandered in search of an optimal environment, then settled to the ground and evolved. Due to its extremely timid personality, if it senses an intruder's presence, it will burrow with the four feet at the base of its body, and completely bury part of its body in the ground. Once it is completely hidden underground, the thing growing from its head assumes the camouflage of a plant, allowing it to defend its body from intruders. However, this is ineffective against herbivorous Digimon.

Etymology
Tane: (タネ) means seed.
