Eeker

Eeker appeared in 2003 video game called Mario & Luigi: Superstar Saga. Eekers are enemies found at Woohoo Hooniversity in Mario & Luigi: Superstar Saga. They resemble beakers wearing grass skirts and holding two torches. Their name is a portmanteau of "eek" and "beaker". They do not show up on the field, but they fight alongside Viruses. The Eeker has two attacks, each with a different counter: its first attack involves crossing its arms and then tilting an equal number of times before charging at Mario or Luigi, which is countered by jumping on it, and its second attack has it charge up with fire and spew out fireballs, which must be countered with the hammer before it releases them. If an Eeker is attacked on offense, but not defeated by Mario or Luigi on his first attempt, the Eeker will immediately charge up with fire so that the next time it performs the latter attack, it cannot be countered before releasing fireballs at one of the brothers.

In the remake, their eyes are no longer red, their feet are no longer in the air, and their first attack has them dancing to music before attacking, making it easier to attack them.
