Step-by-Step Instructions

1

Step 1: Prepare and base coat

Wash and dry your round rock. Paint the entire rock with bright green paint. Apply two coats for a vivid, even color. Let each coat dry completely.

2

Step 2: Paint the big eyes

Paint two large white circles near the top of the rock for the frog's bulging eyes. Make them big and round — frog eyes are their most distinctive feature. Let the white dry.

Step 3: Add pupils and mouth

Add large black circles in the center of each white eye. Paint a wide, curved smile line across the lower half of the rock. The smile should stretch nearly from side to side.

4

Step 4: Add spots and details

Use dark green paint to add random spots or patches on the frog's back. Add a white highlight dot to each eye. Optionally, paint a small red curling tongue at the corner of the mouth.

Step 5: Seal and finish

Let everything dry completely. Spray with clear sealant for a glossy finish that also makes the frog look naturally shiny, just like a real frog.

Step 6: 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, smooth rocks are perfect — they already look like little frogs.
Make the eyes really big and goofy for a fun, cartoon-like frog.
A glossy sealant gives the frog a realistic wet-looking finish.
Use different shades of green for the spots to add depth.
Paint a lily pad on a flat rock as a base for your frog to sit on.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
