Foongus, the Mushroom Pokémon. Foongus release poisonous spores to repel anyone who tries to catch them. For unknown reasons, they resemble Poké Balls.
Foongus, along with its evolution, is similar to Voltorb and Electrode in that it resembles a Poké Ball.
However, unlike Voltorb and Electrode, it only has a Poké Ball design on it, instead of being in the shape of one.
Likewise, it features the whole design, complete with the circle resembling the button in the middle (contrary to Voltorb's evolution line having just the shape and general colors, and according to the Pokédex, being transformed Poké Balls themselves).
Foongus and its evolved form, Amoonguss, share their species name with Paras, Parasect, Shroomish, and Breloom. They are all known as the Mushroom Pokémon.
Origin
It appears to be based on amanita muscaria or mushrooms of the agaricus genus, due to it being Poison-type. The cap is designed to look like the front of a Poké Ball.
Name origin
Foongus is a corruption of fungus and may be a combination of fool (to deceive, referencing its use of its Poké Ball-like cap to attract unsuspecting prey) and fungus. Together with its evolution, their names are a corruption of the phrase, "Fungus among us."
Tamagetake may be a combination of 玉 tama (sphere), 魂消る tamageru (to be astonished), and 茸 take (mushroom, or more specifically, the Shiitake mushroom).
