I need 3 watery sea dragons to be spotted in my garden for my quest but I've totally forgotten how to setup. Would somebody advice me please? Many thanks

Watery Sea Dragons
Step 1 - Plant the Agaric Mushroom and grow to RFH.   
Step 2 - Plant your underwater toadstool, the Mermaid will take you underwater. Alice food is best to attract her.
Step 3 - Put out Veggies on any feeding tables and attract the Watery Seadragon.
NOTE:  Watery Seadragon also eats Wild Berries and Tropical Fruits.
Every 5th Watery Seadragon will plant Red Pondweed if there are "Red Rocks" in your Garden
Beware of attracting frogs if using Berries and high tables.

Thank you very much Agnes. That's very clear and I totally understand it now. Can't believe I had forgotten how to setup.
Since I had a hip replacement recently my mind is all over the place. Many thanks again Agnes.

Sorry Agnes, Do you mean Comfits to attract the maid?

Yes Comfits, only the card gardener and the mermaid can come to them, hope you are soon in full recovery from your hip replacement. Good luck Xx
