I think I just figured something out about the Mushroom Doom card game.

(Okay, for those who are confused: When I was in 5th or 6th grade, I tried to make my own card game, sort of along the same lines as Magic: The Gathering.  Actually, it was pretty much a complete ripoff, though at least it didn't directly copy everything--there were no "mana symbols" and different types of cards had different colors rather than colors actually meaning something, for example.)

But yeah... I think I've figured something out when looking through the sheets of cards that I still have intact.  Most of them seem to be roughly in alphabetical order.  For example, one printed page which has eight cards on it has them arranged this way...

1. Apple
2. Blubbizzo Ocean
3. Boobus Tuber's Castle
4. Burrap
5. Bugg River
6. Carrots
7. Duggrulloo
8. Gold Medal

Basically alphabetical order.  Bugg River is slightly misplaced, but I'm guessing I wasn't really thinking beyond the first letter or two when making these.  A, B, C, D, and then skipping a few to get to G.  Now, here's another example...

1. Homework
2. Kirby Bread
3. Kirby Crystal
4. Kirbyish Rules
5. Kluk'doo
6. Land of the Great Duh
7. Math Book
8. Grapefruit Mountains

Notice how one seems oddly out of place... but if it was just "Mountains," it wouldn't be so unusual to have that one in that position.  I'm guessing that's what happened--when I first came up with the order that I'd make these things in, I was going to just have a generic "Mountains" card, but then I remembered that I actually had a named mountain range in the stuff I'd made up for Mushroom Doom, so I changed the generic title for a more specific one.

And finally... coming around to what I just realized, there's this one.

1. Graveyard
2. Island
3. Julia's House
4. Killer Kirby's Castle
5. Kirby Guards
6. Mushy Room's House
7. Mushroom Island
8. The Rupoo

At first glance nothing looks weird here.  "The Rupoo" is later in the alphabet than "Mushroom Island," so what's wrong?  Well, looking at the others, there's never such a huge jump across the alphabet as this one, and there definitely were cards in between M and T (or R, I guess) in the set.  And the Rupoo, at this point, was definitely not an established character in Mushroom Doom--I'm pretty sure this is its first appearance, and nothing in the other cards ever really references it (aside from one card titled "Cave of the Rupoo," which seems to have been altered before the current version--there's a big chunk of what looks like white space where extra text had been removed.)

The thing I've just realized is... the Rupoo card most likely was not meant to be the Rupoo at first.  Being positioned right after the M's on a page, looking like a scary black glowing-eyed bug thing, with a very high attack power and a side-effect of killing everything except for mushrooms as soon as it comes into play... I'm not sure why I didn't realize until now that the Rupoo card was originally QUEEN BRIDGET.  Which means that the Stage 6 Burijeoo design goes back at least to 6th grade or so, rather than being a later creation.

Now, that makes me wonder if Bigpaw was originally some other Burijeoo-related thing.  He's right in the right place for a name with "Bridgetoid" in it, coming right before "Brigitoo" and "Cave of the Rupoo" (yep, the one with the most-likely-Burijeoo-related removed text!)
