He nodded politely to Tyson. How come I didn't get that much respect? Then he

shot off into the water.

 

Poseidon sighed. He raised his staff, and it changed into his regular weapon — a

huge three-pointed trident. The tip glowed with blue light, and the water around

it boiled with energy.

 

"I'm sorry about that," he told me.

 

A huge sea serpent appeared from above us and spiraled down toward the roof. It

was bright orange with a fanged mouth big enough to swallow a gymnasium.

 

Hardly looking up, Poseidon pointed his trident at the beast and zapped it with

blue energy. Ka-boom!

 

The monster burst into a million goldfish, which all swam off in terror.

 

"My family is anxious," Poseidon continued as if nothing had happened. "The

battle against Oceanus is going poorly."

 

He pointed to the edge of the mosaic. With the butt of his trident he tapped the

image of a merman larger than the rest, with the horns of a bull. He appeared to

be riding a chariot pulled by crawfish, and instead of a sword he wielded a live

serpent.
