on our heels, firing away, and gaining.
Suddenly, there was a big bump ahead of us.
And I mean a BIG BUMP!
âUggo, turn!â
But Uggo didnât turn. He was dead, after all. We headed right for the bump.
FLOOO-OOMP! We hit the bump, and Zeek and I went flying off the skis.
Uggo kept going.
It was amazing to see a frozen dead guy on skis. He raced down the mountain like an Olympic champion. Snow was spraying out behind each ski. He shot down the slopes faster and faster. My dad would have been proud.
âHeâs going for the gold,â I said.
âYeah,â said Zeek, âamazing at his age.â
âPlus, heâs dead,â I said.
Then Uggo flew high over a ridge and disappeared down the other side.
Crunch! We heard ice shattering. Then the skis popped up and landedâ Flunk! Flunk! âin the snow at the top of the ridge.
Suddenly, we heard a roar off to the side. It was Dr. Chill! He was coming in for the kill!
Zeek instantly bent down and gathered up a handful of snow. âStand back, Noodle. This is what Iâm famous for, remember?â
How could I forget? The Pilinsky fastball. Zeek packed the snow until it turned to ice.
âLet him have it, Zeekie!â I cried.
Zeek powered up, pulled back, and fired.
The snowball shot across the mountain.
FWAMP!
Direct hit! Right into Chillâs controls. The snowmobile lurched into a deep snowdrift and stopped. Dr. Chill was buried up to his nose.
He yelled out something, then fell back into the snow.
I turned to Zeek. âDid he say something about a surprise quiz?â
Zeek smiled and shrugged. âI think we just had it, Noodle, and the teacher failed!â
I looked down the mountain and saw my dadâs skis sticking up over the ridge. âLetâs check out Uggo!â
When we got to where our favorite caveman had crashed, Zeek and I stared into the snow.
Our mouths dropped wide open.
We just stared and stared. We didnât breathe.
We were still like that when the rescue team came for us and Dr. Chill. We didnât even say hello. We couldnât. Our mouths were still hanging open.
They didnât close until an hour later, around some delicious double-chocolate birthday cake.
Zeek and I wolfed down most of it while everyone stared.
After a while, we began to talk. We told them about everythingâespecially our discovery at the very end.
âFootprints,â said Zeek quietly.
âGiant footprints,â I said. âIn the snow. Heading away from the empty hole.â
Zeekâs mom and dad just stared at us, as if they were in shock.
Emily made a strange face. âYou mean, Uggo is walking around out there?â
I nodded. ââAncient Caveman Lives!ââ
It was incredible to think about.
No one said anything for a long time.
Finally I turned to Zeek. âBut one thing I donât get. Why didnât you really get frozen when Chill blasted you? I thought you were iced for sure.â
Zeek smiled. âAlmost,â he said. âBut you saved me.â
âMe?â I said.
He dug into his jacket pocket and pulled out a crumpled piece of gold foil. âMy Olympic medal, remember?â
He handed the medal over to me with a smile. It was the foil from my ice cream bar. There was a black mark right in the center where Dr. Chillâs Freez-Beamer had blasted it.
âI did feel weird,â Zeek went on. âBut mostly I was faking it. Itâs like we said, we save the surprises for the bad guys.â
I nodded slowly. âItâs that danger thing, I guess. Itâs in our blood.â
Zeek gave me one of those tiny smiles. Then he said, âYou know, Noodle, it was pretty dangerous today. It will probably be dangerous tomorrow, too. Thatâs the good news.â
âYeah,â I said. Then I thought about it. âBut whatâs the bad news?â
Zeek broke into a big smile. He almost didnât have to say
