Yeah it is trust me, it's so good you should make it.
Carrie, that's a good idea, maybe Jen will be able to help...well the biscuts, we call them Malt biscuts here, i've been looking for a picture of some, and I got this, something called Malt-O-Milk?:

They look like the biscuts you need to use, infact I'm pretty sure, hope you know what they are.
And the lollies, have you heard of Eskimo lollies? They have sort of a marshmellow texture, but harder. And they come in a packet of pink, yellow, green. You could find something simalar, I'm sure. I couldn't find a picture of them, sorry.
I really hope you can make this, it's so good! :P
