This is how the third diamond and Ryan gets possesed and become Prime Prince 9 goes in Crash, Thomas and Ryan ride the Magic Roundabout.

[Zeebad looks around the roundabout but the diamond is nowhere to befound]

Zeebad: Curses! The diamond must be here somewhere.

Sam: [] Zeebad!

Ryvine Sparkle: Sam?

Sam: This Roundabout ain't big enough for the lot of us!

Wuya: When we leave someone for dead, we expect them including Bertatron's twin to die.

Dr. Neo Cortex: Can't you do that right for once?!

Sam: I haven't done anything right since I left the roundabout. Now it's time to resume my post.

Mistress 9: You?!

Zeebad: You were on the roundabout?!

Sam: Yeah. I was. Guarding it from the likes of you.

Megatron (Movie):

Sam: I may have taken a battering. But, it's like what Hugo said. It's what's inside that counts. CHARGE!!!
