Mnemonic

Thick grass grows tall in a midnight field. A night owl swoops down and tucks itself beneath the dense blades, using nature's living curtain to cover its presence completely. No predator can spot the owl hidden under the grass—perfectly concealed until dawn.
Additional thoughts
Picture the owl burrowing under a thick canopy of grass like a blanket. The grass acts as a natural screen, shielding the owl from view. Grass on top, night owl beneath = cover.
Quick recall
A night owl hides beneath thick grass to cover itself from sight.
