When Mareanie sees James' purple face after he gets poisoned by it, she has a strong affection on him, even blushing red. Also, she likes to grab his head using her tentacles.
Mareanie first appeared attacking James because she wanted to eat his Corsola-shaped helmet, but later felt disappointed when it found out that it was only a helmet. After Jessie, who was attacked by her tentacles, gave James a push, she poisoned him, causing him to look like another kind of her species. Thus it blushed and started to chase him, much to his dismay.
