Common Wrong Answers
“A flower”
While flowers can be pretty and may have delicate petals, they do not typically have thorns that draw blood, making them less dangerous.
“A snake”
Snakes can be dangerous and are often found in muddy environments, but they do not have a soft and fragile skin; they have scales.
“A mushroom”
Mushrooms can grow in mud and some are dangerous, but they do not have thorns or the ability to draw blood.
