Blob Thrower

A Blob Thrower is an odd creature in Metroid II: Return of Samus. It spits out blobs that will harm Samus if she touches one. The blob thrower itself is stationary, though. They are found on top of a Chozo building in SR388, and frequently yield large energy units when destroyed.

Without using the Wave Beam, one must fire down at it from above to kill it. The orifice at the top is the weakpoint. The most efficient way to kill it is to wait for it to stop throwing blobs, once it stops it will retract into the ground a small bit, then repeatetly jump over it while shooting down.

The plants found between the platforms during the Nettori battle in Metroid Fusion appear to be Blob Throwers in regard to their appearance and projectiles, though they behave like Samus Eaters from Super Metroid in that these do not appear to be extended and trap their prey.
