Use the eyes with some Miliput/Greenstuff etc. to make Alien/ Cuthulu beasts.
Even better if you don't stop at 2 eyes a creature.
The noses pointing to the sky with something (sisal string etc) coming out of the nostrils
make excellent alien 'plants'. Group several together as clumps, looks even better.
Now, about the squeaky thing.....
N.B. I did run a game where players could only communicate with squeaky things,
though those came from dog toys that our over enthusiastic mutts had broken.
