How Many Legs?

In the forest, the twins find a house.

It is a small and empty house.

There is a note on the old door.

Tim reads the note to his sister.

"I have four legs, but I can't walk."

"People sit on me every single day."

"How many legs do I have? Guess!"

"Four legs, but it can't walk," says Tina.

"People sit on it," Tim says slowly.

They go inside the small empty house.

Tina looks around the quiet room.

She sees four legs under the table.

"Look! It has four legs here!"

"People sit on it. It is a chair!"

A chair has four strong legs.

But a chair can't walk at all.

People sit on a chair every day.

"You are so smart, Tina!" says Tim.

Under the chair, there is a small key.

"Maybe we need this little key."

Tim puts the key in his pocket.

"Three riddles down, five to go!"
