Making Roo your brother?
Having read the whole thread, this is my vote, too. Tigger’s extra bouncy, so he’s got something in common with Kanga; and it’s obvious that Roo must have inherited bounce from both sides, 'cause he’s got so much of it. Tigger’s being over at Kanga’s house all the time is definitely the behaviour of the “uncle” who’s secretly the father.
The Heffalump? Somebody tell whoever said that that the Heffalump is a fictitious character. Get serious, man. 
I think it was a Woozle. I hear they have three dongs.
Imagine someday when Roo is older and has a child of his own. He’ll be going around constantly saying to the kid, “Roo’s your daddy! C’mon, say it, Roo’s your daddy!”
Which will make things really confusing if Scooby Doo is over for a visit.
I read this entire post expecting you to comment on *Booga Roo’s * nickname.
Electric. 
Well, we all know Kanga was stuffed.
The question is by whom.
OK, that was pretty damned funny.
Unfortunately I only thought of it after the thread had wound down, and I didn’t feel right bumping it just to make the joke.
Thanks, flight.
Heresy! As of this year, the mysterious Heffalump has been revealed! Pooh’s Heffalump Movie (2005) shows them in all their splendor when a heffalump by the nickname of Lumpy who’s actual name is Heffridge Trumpler Brompet Heffalump IV, befriends Roo. Their species reside in a place called Heffalump Hollow, on the *other side * of the fence of the hundred acre wood. We shoulda known.

Wait a minute. Roo is the star of this whole movie…perhaps we’re onto something here, because you never see Lumpy’s father, only the mother! Roo’s real father must be Lumpy’s father. That would make Lumpy and Roo half brothers. He probably couldn’t stand the pain of seeing small helpless Roo, the product of one lonely night of reckless passion on the other side of the fence. But the sheer size of the adult Heffalump is astonishing. With that size…Kanga being so small…how could he ever…I don’t see how…oh my.

Then again, it could be a crafty woozle too; a kanga sounds like it may fit together rather nicely with a wooze, thus creating a kangawoozle, Roo’s true species.
Priceless. No, I’m no as sharp as all that.
Unless you’re Scooby Doo - then it would be Erectric 
So Scooby Doo is Roo’s father? Does that mean Roo and Scrappy are brothers?
No, they’d be cousins. Scooby-Dum, Scooby-Dee, Yabba-Doo, Dooby-Doo, Ruby-Doo (mother of Scrappy-Doo), Skippy-Doo and Howdy-Doo are Scooby-Doo’s siblings. They lived near The New zoo Revue by the village of Moo, which had a herd of Shmoo, whose droppings are harvested by wizards to make a powder called Floo.
True, true.
So says you.
Where does Katy No Pocket come in to this? 
I always thought that Eeyore’s tail was torn off due to his mischief with Kanga–and the reason behind his sour disposition, but that’s just a theory o’ mine…
“My name is Inigo Montoya. You killed my great-great-grand uncle. Prepare to die.”
“No, Inigo, I am your great-great-grand uncle.”
“Noooooooo!”
Actually, I always thought the father was This Guy, which also helps to explain why there are no *cats * in The Hundred Acre Wood.

Are the movies Canon? To me, the books are Everything, the movies Nothing.
The movies are fanfic. They are not canon. If Milne didn’t write it, it doesn’t count.
Roo is not Kanga’s child! Roo was born to another couple. Kanga, as a result of an unnatural union with a stuffed elephant, gave birth to a horribly disfigured and twisted kangafunt. In the dark of night, she exchanged her unfortunate love-child with the healthy, normal baby and stole away in the gloom. It was the old switch-a-roo.
I like Snuffalupagus for Roo’s dad. The timbre of it’s voice leads me to believe it is male.
Although referred to lovingly by Big Bird et al as “Snuffy,” I think there are a few clues we should consider:
- While not intellectually agile, I postulate he’s been about for at least a few decades. Plenty of time to give lovely Kanga a little “snuffa-lovin.”
- Anything that big can probably handle multiple vaginas. This would explain his slow, lumbering gait.
- He’s never around when anyone else is, except Big Bird.
- He’s into zoophily (I refer you to item 3).
Just a theory that happens to fit the facts…
