Step-by-Step Instructions
-
Choose your monster and base coat
Wash and dry your rock. Decide on your monster's main color - bright green, silly purple, or vivid orange all work great. Paint the entire rock with your chosen color and let it dry.
-
Add the eyes
Paint one, two, or even three large round eyes on the front of the rock. Fill them with white, then add a colored iris and a black pupil. Friendly monsters often have big googly eyes!
-
Paint the mouth
Add a big wide smile with rounded teeth using white paint. You can make a few teeth slightly uneven for a funny look. Paint the inside of the mouth red or pink.
-
Add horns, spots, and fur
Give your monster personality! Add small horns or bumps on the head, colorful spots, or tufts of fur using short brush strokes. The more details, the more unique your monster becomes.
-
Finish and seal
Add white highlight dots to the eyes for a sparkly, life-like look. Let all details dry fully, then spray with clear sealant. Your friendly monster rock is ready to make everyone smile!
-
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
- Lumpy or irregularly shaped rocks make the most interesting monsters.
- There are no rules - give your monster three eyes, six legs, or rainbow spots!
- Use a toothpick to add fine fur details or tiny dot patterns on the skin.
- Paint the monster's name on the bottom as a fun finishing touch.
- Make a whole monsters family with different rocks and colors.
