A strange seed was planted on its back at birth. The plant sprouts and grows with this Pokémon.
Obviously prefers hot places. When it rains, steam is said to spout from the tip of its tail.
After birth, its back swells and hardens into a shell. Powerfully sprays foam from its mouth.
It keeps its tail raised to monitor its surroundings. If you yank its tail, it will try to bite you.
