Would they meet?

No. Boa and Parasaurolophus did not live at the same time. This meeting is pretend.

What special move did they evolve?

Boa
Branch Drop Wrap
Parasaurolophus
Crest Trombone Blast

Boa

Branch Drop Wrap

They hunt from perches.

Parasaurolophus

Crest Trombone Blast

Air through the hollow crest probably made a low honk.

A secret move here is a real wild tool, not a video-game combo.

THE SCIENCE PICK

Parasaurolophus!

A STOMP

You skipped a final pick. The facts still stamp a champ.

On forest, Parasaurolophus wins. Parasaurolophus is a lot heavier. Boa would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Boa 3 · Parasaurolophus 3 · ties 2.

Your card: Boa 0 · Parasaurolophus 0.

The last page follows the whole animal — body plus home — not one bar chart.
