Shelly

Shelly is an egg from which Birdo hatches in Super Mario RPG: Legend of the Seven Stars. It is a Birdo Egg with pink spots, based on the design of a Yoshi Egg, and it has since become the basis of a Birdo Egg's design. However, during the battle, red splotches are on Shelly instead.
Shelly is fought during the first part of the boss fight against Birdo in Nimbus Castle. Shelly does not attack at all, and Mario and his party merely have to crack Shelly open, by depleting its HP, to reveal Birdo, cuing the main part of the battle.
