A squid-like creature that drifts through underwater stages, homing in on Mario's vertical position. Bloopers move in erratic zigzag patterns — rising toward Mario then darting away — making them difficult to predict. They cannot be stomped underwater.
Swim into from above
Doesn't work underwater
Hug ceiling or floor
Swim straight through
Swim into them from above to bump them away, or hit them with fireballs if you have Fire Mario (note: fireballs do not work underwater in the original game — bump attacks only). Avoid them by staying at the top or bottom edges of the screen.
