Gloom is a dual type Grass and Poison Pokemon introduced in Generation I. It evolves from Oddish at level 21 and evolves into either Vileplume when exposed to a Leaf Stone or Bellossom when exposed to a Sun Stone. Take a look below for 25 fun and interesting facts about Gloom.

1. Gloom is a blue, bipedal Pokemon with rudimentary hands and feet.

2. On its head is a flower with spherical petals surrounded by four reddish-brown leaves.

3. The petals are a dark reddish-brown and have white spots.

4. A female displays a single large spot on each petal, while a male will have many smaller spots.

5. Gloom’s eyes are wide and often appear closed and its lips are thin and purple.

6. Gloom trickles sticky nectar from its mouth with the appearance and consistency of drool.

7. This can be used as a fertilizer for plants.

8. Both this nectar and the flower on Gloom’s head release a foul odor strong enough to induce fainting in humans over a mile (1.6 kilometers) away. 

9. However, it can also attract prey, and even a very small number of humans find it pleasing.

10. This odor is a key ingredient for some perfume production.

11. When it is in danger, the odor worsens, but it will not emit its odor if it feels safe.

12. Gloom lives in grassy plains.

13. In the past, Petal Dance was its signature move.

14. In the anime, James’s description of Gloom’s stench is confused in some sources as a description of his Koffing.

15. Gloom appears to resemble the nocturnal flower known as Rafflesia arnoldii, which has a foul odor.

16. The fact that its terrible smelling pollen can be made into a wonderful perfume and that 1 in 1,000 people enjoy its smell may be a reference to skunks, whose musk has similar qualities.

17. Gloom is taken from the word gloom (a state of depression) and may refer to the gloom associated with smelling its stench or its seemingly depressed face.
