This is my 'awww...' episode. That is, the one that makes you go 'awww...' at the end.
I was trying to build suspense, to suggest that Le Sas may be in danger right up to Panel 6. But then I realised that regular readers would (hopefully) recognise the Yetis and know that they were friendly... (that is, recognise them from Episode 1. Note that Le Sas' 'Dad' is the primary Yeti from that episode: 'Yeti jam?')
I hope this gives some kind of background to the characters.
If you do/have done the 'Which Howler Monkey are you?' quiz on facebook, you'll notice that each result has a brief description. If you are Mad Dog, you are a 'Badass Monkey', because having, and being able to control, the power of the Sonic Scream makes you pretty badass.
If you're Beardo, you're a 'Cool Monkey', because there's nothing cooler than being naturally good at everything.
If you're Smiley, you're a 'Happy Monkey', for the obvious reason that you're seemingly never short of good luck.
If you're Mull, you're a 'Tough Monkey', because of your hard upbringing on the streets.
And finally, if you're Le Sas, you're a 'Scary Monkey'. Because you were raised by monsters.
Pretty cool, hey? ... Um, yes... OK, see you in Series 2...!
[10 Jan '10]: I forgot to mention that this episode is also a tribute to 'The Phantom', with the presence of 'cave monsters', and communicating drum beats as words travelling through the air. I was a mad Phantom collector and fan as a kid...
