Card Trivia:Earthbound Immortal Chacu Challhua
- This card is based on the orca geoglyph of the Nazca Lines.
- "Chacu Challhua" is derived from chuqi challwa, the Quechua word for anchovy, where the Peruvian anchoveta is common in Peru.
- This card is tied with "White Aura Bihamut" for having the highest Level (10) of all Fish monsters.
- This card is the first and so far only "Earthbound Immortal" monster to have two unique effects.
- "Earthbound Immortal" monsters often represent their card's owner and their initial ambitions and desires; in this card's case, it represents Greiger and the children he looked after in his home country.
- Whales are known for having large families and traveling in groups, reflecting Greiger's bond with his younger siblings and the large group of orphaned children in his village.
- Orcas (more commonly known as "killer whales") are aggressive creatures that ae known for fiercely hunting their prey. This reflects how Greiger initially wanted to kill Rex Goodwin for being responsible for destroying his village and killing his family. This was later proven to be untrue, as this monster is revealed to be responsible for the destruction of the village and the absorption of the children's souls.
