Hidden Bug Surprise Frankie Cauldron Bath Bomb
A spooky little bath-time surprise is hiding inside Frankie…
This small green Frankie cauldron is packed with our fluorescent colour-changing bath bomb mix. Add it to the bath and watch the slightly suspicious green mixture burst into a much brighter Toxic Green as it meets the water.
As the colourful fizz dissolves, a reusable toy scorpion is revealed from inside. It is a brilliant wee Halloween treat for children who love creepy crawlies, surprises and colourful potion play.
The lightweight plastic Frankie cauldron can be rinsed, dried and kept for imaginative play after bath time. Each one includes one filled cauldron and one hidden scorpion toy. The scent is selected at random.
Hand-filled in small batches at Boddle Bath in Uddingston, Glasgow. Colours and finishing details may vary slightly.
What’s Included & How to Use It
You will receive:
- 1 small green Frankie plastic cauldron
- Fluorescent colour-changing green bath bomb mix
- 1 reusable toy scorpion hidden inside
Place the cauldron in warm bath water and let the mixture fizz out, or gently dip and tip it during supervised potion play. The concentrated mix changes from a duller green into a much brighter fluorescent Toxic Green in the water, gradually revealing the hidden scorpion.
Once empty, rinse the cauldron and toy thoroughly with clean water and allow both to dry completely before storing.
Important Safety Information
For supervised bath-time play only. Recommended for children aged 3+.
Contains a small reusable toy scorpion which may present a choking hazard. Keep away from children under 3, do not allow any part of the product to be placed in the mouth, and remove the toy from the bath once revealed.
Bath bomb products are not food or drink. Avoid contact with the eyes and broken or irritated skin. The concentrated powder may temporarily transfer colour to wet fingers; this should wash away like a water-based felt-tip pen. Rinse the bath with clean water after use.
Stop use if irritation occurs. Please check the product label before use if your child has known allergies or sensitivities.
Maker Info
The bath bomb mix is handmade, safety assessed and hand-filled by Jen and the Boddle Bath team in Uddingston, Glasgow.
The Frankie cauldron and scorpion are reusable plastic play pieces. They are not handmade or 3D printed by us. As each cauldron is filled in small batches, the exact colour pattern and finishing details may vary slightly.
Storage
Keep the filled cauldron somewhere cool, dry and away from direct sunlight until you are ready to use it. Moisture and humidity can start the fizzing reaction early, while strong sunlight may fade the colour.
For the brightest colour and best fizz, keep it in its packaging and enjoy within 6 months.
