Lots O'Jelly Fish

Lots O'Jelly Fish is the first Ocean level in Yoshi's Story. Most of the level seems to be a large underwater maze filled with various fruit and dangerous creatures. As stated by the title of the level, Jellyfish are the most common enemy in the level. Several of these jellyfish have fruit floating inside their bodies, which can be eaten by a Yoshi by sticking out its tongue. Parts of the level take place on an island (or islands) above the main level. The level also contains an area specifically for one enemy, the Snorkel Snake. This area is a small "X"-shaped cave to make it easier for the fish to poke a Yoshi. Other enemies include Sensuikan Heihō, Spiny Cheep-Cheeps, Tehee Butterflies, Cheep Cheeps, and Sea Cacti.

''To go any farther, the Yoshis had to brave the Ocean. They jumped in! They liked to swim, but the jellyfish's sting spoiled their fun. So they swam to dry land. Now they were almost to the end of the book!''
