I am sure I am correct but maybe my brain is frazzled I have berries out on high plate & a empty plate for spawn
My frog breeding count is as follows
SPOTTED       89 Tadpoles      56 Froglets      should mean I would get 56 land frogs in my garden
Land Frogs attracted are 54
Land Frogs spotted are 25 (but I know that count does not matter)

ATTRACTED    69 Tadpoles     65 Froglets      65 Underwater Frogs  (meaning zilch spawn underwater)     

Any ghostly frogs spotted?  You have to add those to the underwater frogs to work out if any frogs are due.  As you've only got a couple in hand, it could make the difference between having one due,  or not.

Many thanks the penny has finally dropped I was not counting how many U/W frogs plus the 1 ghost froggy which is 55 so I need to spot 1 under water frog for spawn oh my days this game certainly gets you in a tangle
