Menie and Monnie soon reached Koko's igloo. Menie and Nip got there
first. Monnie came puffing along with Tup just a moment after.
Then the twins dropped on their hands and knees in front of Koko's hut,
and stuck their heads into the tunnel. Nip and Tup stuck their heads
in, too.
They all four listened. There was not a sound to be heard except loud
snores! The snores came rattling through the tunnel with such a
frightful noise that the twins were almost scared.
"They sleep out loud, don't they?" whispered Monnie.
"Let's wake them up," Menie whispered back.
Then the twins began to bark. "Ki-yi, ki-yi, ki-yi, ki-yi," just like
little dogs!
Nip and Tup began to yelp, too. The snores and the yelps met in the
middle of the tunnel and the two together made such a dreadful sound
that Koko woke up at once. When he heard four barks he knew right away
that it must be the twins and the little dogs.
So he stuck his head into the other end of the tunnel and called, "Keep
still. You'll wake the baby! I'll be there in a minute."
Very soon Koko popped out of the black hole. He was dressed in a fur
suit and mittens just like the twins.
