How Hattrem compares to the real Flower Hat Jelly
Hattrem's official category is the Serene Pokémon. AnimalDex rates its resemblance to the Flower Hat Jelly as a broad match, meaning the animal is one influence in a largely fantasy design. Hattrem's bell-shaped pink body and whipping braids are mainly a witch design. The flower hat jelly is the closest real animal, a hat-shaped jellyfish whose trailing tentacles echo the braids Hattrem lashes out with.
The comparison covers looks and behavior cues, not biology: Hattrem is a fictional Pokémon, while the Flower Hat Jelly (Olindias formosus) is a real animal. On AnimalDex the real Flower Hat Jelly scores 36 for dominance, 8 for speed, 10 for size and 3 for intelligence, out of 100, so its strongest trait is dominance.

Olindias formosus
The Flower Hat Jelly teaches moving beauty. Its form is delicate and drifting, but its presence still changes the water around it.
How to recognize it

- Tentacles grow from the bell's upper surface as well as its rim
- Tentacles tipped with bright pink, purple or green
Real Flower Hat Jelly facts
- Its tentacle tips contain fluorescent proteins, and in aquarium tests young rockfish swam towards them, suggesting the glow lures prey.
- Its sting causes painful red welts on swimmers but is not considered life-threatening.
- Diet
- Mainly small fish, caught on tentacles armed with stinging cells, along with small crustaceans and other plankton.
- Lifespan
- Lifespan of the jelly stage in the wild has not been measured; it probably lasts a few months.
- Predators and threats
- Specific predators of this jelly have not been documented. Its dense stinging cells make it a poor meal for most small fish, and strong currents and storms can strand it.
