Yodoyo Sea
ヨード液シー
Yodoyo Sea is a Battle Cats stage in Secluded Cavy Island. It costs 200 energy and sends 6 enemy spawn lines — led by Techn-Old Hyena as the boss — against a 1,111,111 HP enemy base, and clearing it rewards 482,220 XP. Its enemies carry the Black, Alien and Sage traits, so cats that target them do the most work here.
