Speed

— starring mirabelle —

Mirabelle is trying to measure the speed of a surprisingly sneaky tortoise. Every time she looks away, it leaps out of its shell and steals some of her lettuce. Eventually it runs away, and slides down a hill on its shell, but gets bounced back towards Mirabelle by a low branch. Mirabelle measures the tortoise's speed as it flies past, and records that tortoises are faster than cheetahs.
