Pretend to look through a magnifying glass.
Rub your hands together like a sneaky plan.
Wave your hands in the air cheerfully.
Give a thumbs up for good hygiene.
Mime washing your hands properly.
Hold your belly and laugh like a villain.
Pretend to gobble up a wafer eagerly.
Stroke your chin thoughtfully.
Flex your muscles like a strong superhero.
Pretend to be in a tug-of-war between clean and dirty.
Put your hand on your heart, deciding to be healthy.
Raise your hand as if taking an important vow.
