Slark has been sculpted from Super sculpey - some pieces like the fins on the top of his head are sculpted from Milliput. His teeth are made from Fimo translucesent white. Have a look at some of the progress pictures would you?
For the drool a mixture of clear glue and Deluxe Materials Making Waves is used.
The shoulder fish - is that's what it is - has toy eyes which are usually reserved for bears and creepy dolls.
For the tail - which needed to be long and thin - I used a mesh from a magazine rack to allow for a strong, thin armature.
The rock for the base was created by taking a mold of a rock from the beach and then pushing some DAS clay into the silicone mold to cast it.
I embeded some more magazine rack mesh into the DAS clay to make sure the finished 'cast' was strong - I wasn't sure just how strong this stuff was when it set.
