When building the head, put the tongue into the mouth before the teeth. 
The teeth should just be slightly rolled like a cone, so they resemble teeth- 
actually using the tabs may be difficult, due to the size. Once they're built, just
put a little glue inside and press them in place. If there's enough glue, they should 
set in place. 

Build the wings normally, and line the edges of the 'webbing' (66-67, 80-81) lightly with 
glue. Press them in place similar to the teeth. Do the same for the webbing of the fingers,
being sure that the fingers are in place already.
