Googol and Googolplex's spaceship makes a soft buzzing noise and it is invisible to humans. Pippa thinks a bee is flying around them. She waves her hands to shoo it away.
Troy stands up in the pool. The buzzing stops. He smiles.
"It's not a bee, silly. Look!" he says.
Pippa turns her head just in time to see Googol and Googolplex roll down the ramp out of their spaceship.
"Googol! Googolplex!"
Troy and Pippa jump out of the pool and run toward their friends.
