Made for little days

Nothing to do in the water
When the pool gets boring, drop the shell. It fills with water, sinks, then pops open on the floor and the mermaid spirals up.

Pick what you get
Choose one shell in clear pink, hot pink or clear blue, a pack of two shells, or two extra mermaids. Mermaid styles are sent at random.

One more dive
Kids unsure about looking under the water get curious about the mermaid. Every dive is a little reveal.

Questions
Good to know
Does it work in a regular bathtub?
It's made as a pool dive toy: the shell opens when it reaches the pool floor. In a bath, results depend on water depth, so think of it as a pool toy first.
What do I get with each option?
Single shell options come in clear pink, hot pink or clear blue, and are pictured with a mermaid. You can also choose 2 shells or 2 mermaids.
Can I choose the mermaid style?
No. Mermaid styles are sent at random, so the hair and tail colors may differ from the photos.
What age is it for?
Ages 3 and up. The mermaids are small parts, so keep them away from babies and younger siblings.
How much is shipping?
Shipping is free on every order within the United States, with no minimum spend.
How long will my order take to arrive?
Orders are prepared in 1–2 business days. Most orders arrive within 2–4 weeks, and some items can take up to 30–60 days depending on the item, your location and busy seasons. Shopping for a shower or a due date? Please order early.
How do I track my order?
As soon as your order ships, we email you a tracking number. Tracking can pause for a while in transit, so a gap in updates doesn't mean your package is lost.
What is your return policy?
You can return items within 30 days of delivery if they are unused, unwashed and in their original packaging. Defective, damaged or wrong items are free to return. For change-of-mind returns, a $10 return shipping fee and a $10 restocking fee are deducted from your refund.
Is there anything I can't return?
For your baby's health and safety, we can't accept items that go in the mouth or against the skin once they've been opened, used or washed. Unopened items in sealed packaging can be returned as normal.
