LOL! Sorry--the title of your thread made me expect one of those "Find the oddball thingy in the picture" kinds of games.
First blooms on slippers will very often open deformed. In fact, many growers won't even let their plants' first spikes develop through maturity, cutting them off just as the buds start to form for that very reason.
Absolutely nothing at all to worry about--looks kind of cool, actually!
