What if the brocolli was swelling with some kind of... vegetable gass, maybe it could imitate movement and walking if it is being dragged along, and maybe make vegetably cute sounds as gass escapes occasionally?

Yea, and then it raised one of it's little broccoli legs and farted real loud and it smelled just like rotten cabbage!

Smelled like cabbage?
Mrs brocolli will be heartbroken!
He better cover up that smell before he finishes his walk!

Yes, but that's not all! I saw him out with a really nice tamata.

Wow! What a sleeze!
I heard it was a guy tamata too, that mr broccoli must be a real fruit ;)

No, he is a Bivegetable.

WEIRDO's

No, You're the WEIRDO.

Um... OK! I will let you be right... LET YOU... I said!

And besides that, he ate a cute little cucumber and got Burpies!

Cute little cucumber? How could that be?
