Basic info

Kadokawa guidebook
This magic plant is a type of palm tree that grows wild in the central part of Tahiti Island in the South Pacific. It was bred by a wizard who visited the region long ago. It flaps its head leaves and moves around gaily.
JICC guidebook
It's a monster with legs and eyeballs on a palm tree. When it closes its leaves, it becomes an Egg-Man in a different color rather than a palm tree.
The name Yahinotkin is based on the palm tree in Japanese ("ヤシの木", pronounced Yashinoki).
"Egg-Man" in the text is this monster.
