Weird Dessert

I have eaten all sorts of weird shit: offal in Rome, chargrilled lambs tail, tongue, brains and fish eyeballs etc.
The weirdness now extends to Vietnamese desserts.  My colleagues are real food nuts!  They sell their desserts in the work canteen, you can also buy spring rolls fresh deep fried or frozen.  There is also prawn sticks that are wedged onto stalks of bamboo shoot (I think).
The dessert is mostly coconut milk with green food coloured noodles floating around like gizzards, and then there is some ice and some chewy ice looking glutinous stuff - No idea what that is?
