Even Your Skeleton Works Overtime Down There
Your tank is quiet.
Fish drift by. Same rocks. Same plants.

Then you drop Finnegan in — and suddenly a tiny skeleton starts pushing a waterwheel, bubbles rising with every turn.
It never stops.
Your fish don't know what to make of him. Neither do your guests.
One Of Our Most Reordered Tank Ornaments This Year
✓ Your tank, finally in motion
The skeleton pushes the waterwheel non-stop, powered by rising bubbles. Movement your eye can't ignore.

✓ No batteries, no cords, no worry
Hooks up to any standard aquarium air pump with the included tube connector. That's the whole setup.

✓ Safe for your fish
Made from fish-safe PLA with no metal parts and no dyes leaching into the water. Rinse it, drop it in, done.

✓ Stays exactly where you put it
The weighted rocky base holds firm on gravel or sand. No floating, no tipping, no chasing it around the tank.

Frequently asked questions
Does it need its own air pump, or does it come with one?
It comes with an air pump, so you have everything needed to set it up. Simply connect the included tubing and plug it in.
How strong does the air flow need to be for the wheel to spin?
A gentle, steady flow from a basic aquarium pump is enough. If the flow is too weak, the wheel slows down. Too strong, and bubbles rush past the paddles.
Is it safe for freshwater and saltwater tanks?
Yes, it works in both. The PLA material won't leach or rust, and there are no metal parts.
How big is it?
The base is about 4 inches wide and the whole piece stands roughly 4 inches tall. Good for tanks 5 gallons and up.
Specifications
- Size: 4" wide × 4" tall
- Material: aquarium-safe PLA
- Powered by: standard airline tubing (air pump included)
Do these run true to size?
They fit true to size for most. If you're between sizes or prefer a slightly relaxed fit through the hip, we suggest sizing up one.
How tall is the model, and where do the pants hit?
The pants are designed to sit at the ankle on a 5'7" frame. On taller women, they will sit slightly above the ankle. On shorter women, they may fall between mid calf and ankle length, depending on height and proportions.
Can I wear these to the office?
Yes. Paired with a tucked blouse and loafers, they read polished and professional. The tapered cut keeps the silhouette clean.
Will the fabric fade after washing?
The cotton-linen like blend is pre-washed to soften the hand feel and minimize fading. Wash cold and hang dry to keep the color rich.
