So it would seem that after seeing one of Nozo's baby pictures, Keco somehow managed to distort the timestream and travel back in time, to give my little girl a plush toy of himself. Of course, me and Nezu were puzzled where it came from, as at that time we didn't know who Keco was!
...and it took some getting used to with dealing with that thing at night. o.o Not sure what the deal is with that toy, but Nozo's still got it up on her shelf.
