Yeah, I guess that's true.

And you guys are probably right that, once out of the canon world, the invincibility would be pretty much gone. Maybe...

But would it work both ways, I wonder? If an agent or a Sue from a different universe is killed in the Happy Tree Friends universe, would they come back, too?

Also, is there an established Mini for Happy Tree Friends? I was thinking, if there isn't, maybe a Mini-Idol or a Mini-Whistle.

The elves just took their time about it, so when the Flowers scanned, the Sue showed up as still alive.

True. Too much risk of it simply leaving them alive but in pain forever, and Sues being Sues there's too much chance of them escaping. Also need to make sure the agents don't go in to watch it first-hand because if the Holder sees them, they probably have to pass its test to get out, and they'd probably rather fail the test than face the Flowers after having brought an Object into HQ. Though if they went to see the Bride of the Seeker, they could get rid of the Object that way, because if they pass her test but aren't the Chosen, she gives them the option to get rid of the Object and forget all about the Holders. Could work with that.
