Yoshi's Island Spring Water

Yoshi's Island Spring Water is water found in Yoshi's Island during Mario & Luigi: Partners in Time. There were Yoshi statues around the island, and one of the had a hole where the spring water was coming out.

Next to the statue was a sign that read "Yoshi's Island Spring Water. A healthy yummy drink ideal for growing kids! Remember: Drink like a pig...and your belly will get big!"

Baby Mario must drink some of this water to get full of water, and then make Baby Luigi hammer him and then Baby Mario will spit the water out. This move is useful in many areas.
