Recently my parents and I met up with one of my Mum's best friends, Aunty Alpa. As usual I took my sketch book with me and as I was drawing, Aunty Alpa said she loved my Space Plops. I made a really easy step-by-step guide for her so that she could learn how to draw them. Here are some pictures -- Aunty Alpa drew herself as a Space Plop (the one called Alpa) and I drew me as one -- I'm the one with the afro :)
Why don't you try creating some yourself?
