The image shows approximately 16 choanocyte chambers, each about 30 micrometers in diameter—about the size of a pollen grain. The green color marks the flagella—hair-like structures that pump the water. The red color marks the cytoskeleton, which includes a structure called the collar (not visible here) that captures the prey. The light-blue regions mark the nuclei of individual choanocytes.

Smells like Krabby Patties…
choacocytes: collar cells
flagella: little whips
(frantically matching colors of knitting yarn)

That is the appropriate reaction.
