After lunch they went to the reptil

After lunch they went to the reptile house. It was cool and dark in
there, with lit windows all along the walls. Behind the glass, all sorts
of lizards and snakes were crawling and slithering over bits of wood and
stone. Dudley and Piers wanted to see huge, poisonous cobras and thick,
man-crushing pythons. Dudley quickly found the largest snake in the
place. It could have wrapped its body twice around Uncle Vernon's car
and crushed it into a trash can -- but at the moment it didn't look in
the mood. In fact, it was fast asleep.
Dudley stood with his nose pressed against the glass, staring at the
glistening brown coils.
"Make it move," he whined at his father. Uncle Vernon tapped on the
glass, but the snake didn't budge.
"Do it again," Dudley ordered. Uncle Vernon rapped the glass smartly
with his knuckles, but the snake just snoozed on.
"This is boring," Dudley moaned. He shuffled away.
