They both dashed behind a bush. Unforgivable masses of eggshells were flying through the coal black sky. Birdo tried shooting yolky projectiles at them, but they kept dodging. Fire and eggs flew everywhere, but she couldn't help. They ran at the speed of light towards the gloomy forest. It was their only way to escape…

"Look! A Boo Mask! Just what we needed! Birdo exclaimed over the war cries of the Birdo Squad.

They hid under it, both of them, and headed deeper in.

"FIRE!" Yoshi screamed. It was Green Birdo!

Yoshi stood up, ready for combat. He took of the mask, and then wrapped Green Birdo in his tongue. Boos were coming from all nooks and crannies, but Yoshi jumped back into the mask, and Green Birdo was never seen again. They dashed off into the darkness, but nothing stopped them. The rest of the Squad was far behind them.

"YEAH!" Birdo hoorayed with spirit.

BOO!

The ghost didn't even mind them being there. They trekked onwards, until they had numb feet. They couldn't continue running after that, and Red Birdo was trailing behind, along with Blue Birdo and Light-Blue Birdo. They were doomed!

POW!

Yoshi was punched to the ground! The Boo Mask fell right of both of them. As soon as it fell off, the Boos started on them. Birdo and Yoshi were hungry. They needed dinner, but they were dinner!

Red Birdo cracked his muscles.

Blue Birdo chuckled.

Yellow Birdo smiled dangerously.

The Boos all laughed

BOOM!

The floor broke! They had fallen into a trench!

The Birdo Squad jumped down into the hole, and the Boos floated down.

The Troublesome Twosome put on the mask, and the Boos changed direction. Wow, they were stupid! They dashed along the trench, but boulders of iron and rock were falling in on them! There was a rocky ground above, and clearly wasn't too solid.

They attempted dodging the rocks, but Birdo's leg got caught underneath one. She screamed in agony, before Yoshi pulled her ankle out of the rocky chunk. With Yoshi's support, she could continue, even with her broken ankle.

Now Yoshi's abilities were coming to use. Time for the excellent flutter jump! Up the wall they went! Yoshi couldn't get high enough, so he used his tongue to swing him up the wall. Now the Birdo Squad were trapped in the trench!

"Au Revoir!" she said as she departed them.

"RRRRRRGGGGHHH!" Red Birdo growled.

Hang on! Boos were dragging them away. Did they know they weren't Boos?

But the Troublesome Twosome stayed calm. What was going to happen next?
