The Gang is playing a character guessing game.
Cera: "Who is it?"
Spike: :mad
Ducky: "Yes, it must be someone really mad, yep, yep, yep!"
Petrie: "Me dunno!"
Littlefoot: "Is it OZZY!?!"
Cera: "Yep, and he'll throw the little annoying Lockneck from the Great Wall NOW!!!"
Littlefoot: :huh: ... :blink: ...

(Seriously, Cera's expression looks sooo similar to Ozzy's

)
