Does anyone recognize this monster family board game?
The game is called Creepy Towers. 


The box was shaped like a creepy castle or house and there was a
laughing skull piece 
and you had to go through the house (which may
have been the box)




From the publisher's description:


  Includes light-activated laughing skull





and all your player pieces were tiny brightly colored skulls 
I think there was a rubber spider too… 




From the publisher's description:


  Includes ... two rubber creatures





It would have been between 1993-1999


The game was published in 1995




Actually came with a book


From the publisher's description:

And from the BoardGameGeek entry (linked above)


  Within Creepy Towers there is a board game, short story
