However, I managed to hunt down Flippy recently. He's probably one of the harder to find(i think people like his dogtags), so I'm glad to have finally acquired him.
He's now on my bookshelf, amongst the 4 other characters I own(& a handful of other plushies).
One day I shall complete the set, by that point the entire back section of that shelve will be filled with HTF goodness. I really do love plushies, it's too bad they take up such an excessive amount of space! For this collection however, it's worth it.
