1.) Choose a life-form.
2.) Fashion pieces. If the form has a body and appendages treat it like you would a skeleton. If the bones separate at the shoulders, then form the piece out of 3-D media. Tinfoil is a good beginning place especially for young children. You may want to roll and compact the tinfoil into tubes that can then be bent and pressed together.
Alternatively bind sticks with twine, or work with clay.
3.) Apply a finish or surface texture. Here we used a bright red tempera paint to give the squid presence and draw the eye. Perhaps it is a vampire squid from the deep ocean trench depths. Whale-forms and other sea mammal forms also lend themselves well to this kind of treatment.
