Toadpoles not Tadpoles!

What's up Rory?  Henry asks.

There are no tadpoles...Rory replies.  Look.

Henry has a look.  

The pond is full of them!  He exclaims.

Rory sighs...

They are toadpoles.  He tells Henry.

Henry looks again.

What do you mean 'toadpoles'?  He asks.

Rory explains.  That is what I call toad tadpoles...toadpoles as they are not frog tadpoles.

I wanted frog tadpoles.  These never seem to develop much further than what you can see in the pond now.

They get little legs...and then one day overnight they will all disappear until next year when the pond will be filled with loads of toads again.

Well that is strange.  Henry says.  I wonder why they disappear?

I don't know, says Rory...it is a mystery to me. I thought at first they got eaten in 2020, but in 2021 and 2022 the same thing happened.   That is why I want tadpoles from frogs so I can watch them develop fully and hear them croak.

Don't toads croak?  Asks Henry.

Not sure, says Rory.  I've never heard them do so.
