Wait, what's this? A new Creepy Freak that's not a repaint?!?!? Rejoice! Daisy here is a mutated Venus flytrap -- not unlike Audrey II of Little Shop of Horrors fame -- so while it's not a completely novel idea, the adaptation does work quite well for the Creepy Freaks line. Also, whereas most versions of Audrey II (and most flytrap creatures in general) lack eyes and proper limbs, Daisy has both a set of peepers and branches with leaves that respectively resemble arms and fingers. This effectively makes her look almost like some sort of plant-dinosaur hybrid, which is kind of a neat idea that I'd like to see explored in fiction (or, even better, claymation film). Daisy's not quite as creepy or freaky as she could be with the proper characterization, but she's definitely one of the cooler Creepy Freaks.
Also, given that Daisy was packaged differently in the box -- whereas most of the Creepy Freaks come in a sort of basket structure not unlike a squared cupcake holder, Daisy came in a front-facing plastic shroud fitted to her shape (think of upright sarcophagi lids and you're on the right track) -- I'm going to assume that she was one of the rarer figures. Also, given that it's sort of possible to tell whether a box has a figure like this in it by shaking it (her packing permits her to move far less and thereby make less noise), I can imagine kids sifting through the Creepy Freaks boxes and shaking them in attempts to discern which ones had the rarer figures with the oddball shapes. Konata would have, anyway!
And here's Mad Jack, whom we've seen before. We have not, however, seen him before with two attached arms! So while he's not a new figure per se, I'm about as glad to see him as I am to see Venus -- making this about the best booster set we've seen in quite a while. It really doesn't get much better than dino-flytraps and insane clowns, folks.
