aha! I knew there had to be a level on the christmas tree eventually!
on first loading the level...
okay, there's a guy on his cellphone. There's a santa. Cellphone guy drops the phone into the sewer after banging into santa and is very upset.
Then a... guy in funny makeup waving a love letter jumps out of the phone and is washed down the sewer? WTF?
... partway through the level I *think* he's the signal trying to deliver the text message that was being sent when the phone was dropped? Maybe?
