RETNA

RETNA is the first dimension in game. It is a small, grassy dimension with three clouds. Wooden construction covers a majority of this dimension, cancelled due to attacks by BIT BANDITS and THUNDERCHICKS. RETNA's enemies include THUNDER CHICKS, BIT BANDITS, INVERTUS, and the boss OCULAX. Trading RETNA's Mega Coin to shop would reward you with a Ranger Hat, which would increase your attack and defense rather slightly.

NPC's in RETNA include Brian the shopkeeper, and Jared the helper.

Facts
RETNA was named because its boss: OCULAX, uses its eye as its weapon, RETNA is a similar word to the retina, a vertebrate in the eye.
