Lucy woke up. Her sister Thabi wasn’t in her bed.
"Thabi’s in the kitchen eating breakfast."
"Where’s Thabi?" Lucy asked Ma.
"That’s not Thabi!" "That’s a hippopotamus!"
Lucy looked all over the house.
"Where’s Thabi?" Lucy asked Pa. "Thabi’s swimming in the pool."
"That’s not Thabi!"
"That’s a hippopotamus!"
Lucy kept looking around the garden.
"Where’s Thabi?" Lucy asked the neighbour. "Thabi’s playing in the park."
"That’s not Thabi!
That’s a hippopotamus!"
Then Lucy heard a funny noise. She gave the hippopotamus a big tickle.
"There’s Thabi!"
"Thanks," said Thabi. "It’s very boring inside a hippopotamus."
