Tortoiseshell Shock
Our neighbour’s tortoise Harold would constantly escape from their garden, often warranting a large search party to find him. My father, who was a scientific engineer, offered to build a tracking device. Our neighbours gratefully accepted.
The small box was glued to the top of Harold’s shell with engineering epoxy and my father said we could track it down in minutes if he escaped. The day after the device was attached, they found Harold trying to escape under the fence.
Funnily enough, the tracker didn’t need to be used that time, because Harold couldn’t get under the fence due to the box glued on his shell!
