I'll say right away about the murder...
Krabby was probably an elf, since there's no carrot or bucket, and he was killed by a snowman-maniac)... but at the same time, you could think that he might have been a snow woman who blocked Cash, sticking matches in the lock and not letting him out... but would a snow woman do that? because she plays snowballs) so the version is that a snowman-expert came to Cash and broke his lock, because it turned out to be bad! ... or maybe the matches are a clue =\
