mountains. Iâll have to land.â
Kai landed the jet. Then he set it to stand-by. âI can call it with the orb if we need it now, BC,â he said.
Kai grabbed the orb and locked it into the X-Foam Archer. He put the Archer on his back. Then he grabbed his hover board. âHop on, BC,â he said. âItâs time to follow these egg shells and see where they lead.â
Kai and BC hovered above the eggshells. âThe shells lead in there,â said Kai.
Kai pointed to two tall rock mountains. In-between the mountains was a narrow path. âWe have to go through those mountains,â said Kai. âThe track is small but we can fit.â
Kai and BC moved slowly onto the path. âItâs too dark in here,â said BC. âIâll use my laser light tail.â
BCâs tail lit up the space.
Suddenly there was a terrible noise.
Â
Â
Then rock bats flew at them from everywhere. âThereâs so many of them,â Kai said. âAnd more are coming.â
âWatch out,â said BC. âTheyâre dropping slime! Iâll get them with my eye lasers.â BC hit the bats one by one with his lasers.
Iâve seen that slime before, thought Kai. He took his orb from the X-Foam Archer. He hit a button. A metal arm shot out from the orb. The arm scooped up some slime. Then it went back inside the orb. Kai waited for the screen to flash.
I knew it! he thought as he looked at the screen.
Itâs the slime from the water land. But why is it here? thought Kai.
âTop job with the bats, BC,â said Kai. But something strange is going on here.â
âVery strange,â said BC. âBut itâs safe to go out now.â
But then BCâs tail began to wag. âBeast is coming,â he said.
âWhere?â asked Kai.
âThere,â said BC. âLook!â
BC pointed to a pile of rocks. Kai saw the rocks move. He checked his orb.
Kai loaded an arrow into the X-Foam Archer. âIt has an ancient arrowhead on it.â
Kai got ready to shoot. He was about to let go of the arrow when he heard a loud noise.
Â
Â
âWatch out!â said Kai.
Rocks and dirt flew from where the beast was standing. They crashed to the ground. A pile of smoke and dust filled the air.
Then BCâs tail wagged like crazy.
âWhat is it, BC? I canât see through the dust.â
âBig danger ahead,â said BC. They both waited for the dust to clear. And then Kai saw it. âWhat is that thing?â asked Kai. âIâve never seen anything like it. This is bad.â
Standing where the rock beast had been was a beast with two heads. Kai grabbed his orb and took a photo. Kai waited for the card to come on his screen.
âWhy is it taking so long?â asked Kai.
âMaybe orb is mixed up too,â said BC.
At last a card popped up.
âA mutant beast!â said Kai. âWhat is that?â
âMix-up of some beasts,â said BC. âThe heads are rock beast and water beast.â
âHow do we battle it?â asked Kai.
BCâs tail wagged again. âNo!â said Kai. âNow what?â
âBeast won against the rock beast,â said BC. âSo it can grow. Look!â
Kai took another photo with his orb. He looked at the card and began to think.
âFour arms,â said BC. âTwo can shoot things like the rock beast. How did this happen?â asked BC.
âI think we did it,â said Kai. âWhen we battled beasts we mixed the worlds. We used water on the rock beast. We used ice on the fire beast. We mixed things up. Now the beasts are mixed up too.â
âThis is bad,â said BC.
âVery bad,â said Kai. âNo more mixing. We must battle with rocks, dirt and dust only.â
Then the beast lifted its arms. âItâs getting ready to attack. Quick, letâs go.â
Kai and BC hovered up high above the beast. But
