Step-by-Step Instructions
-
Prepare and base coat
Wash and dry your rock. Paint the entire surface with bright green acrylic paint - the classic alien color! Apply two coats for full coverage and let each dry completely.
-
Paint the enormous eyes
Aliens are famous for their huge eyes! Paint two very large oval eyes taking up most of the upper face. Fill them with white, then add a large black iris and a tiny white highlight sparkle dot.
-
Add the face features
Paint a tiny, simple smile or a curious expression - aliens can look friendly or mysterious! Add two small dot nostrils and oversized pointy ears on the sides of the head.
-
Add antenna and details
Paint two thin antennae on the top of the head, each ending with a glowing dot in yellow or purple. Add silver or purple spots on the head for an out-of-this-world texture.
-
Seal your alien
Let all the details dry completely. Spray with clear sealant. Your alien rock has landed and is ready for its mission on Earth - or on your shelf!

Add RoxGeo Code
On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.
Helpful Tips
- Round rocks with a slightly wide top naturally look like alien heads.
- Make the eyes extra large - alien eyes are always the star of the design.
- Try a grey or blue alien instead of green for a more mysterious look.
- Glow-in-the-dark paint on the eyes and antenna dots is amazing at night.
- Add a small UFO or planet painted on the back of the rock for a surprise!
