Meaning of "to be over the moon"

[Jupiter]

Hello teachers

I have learnt several expressions which mean we are happy.
Here are they:

To be over the moon.
To be on cloud nine.
To be in seventh heaven.
To float on air.
To walk on air.

Could you please share me some more expressions as above?

Thanks in advance

Hi Jupiter

Here are a few more:

- on top of the world
- chipper
- pleased as punch (also written: pleased as Punch)
- happy as a clam
- happy as a flea at a dog show

(There are quite a few possibilities with the "happy as a" format. But the two I listed are quite well-known in AmE)

Hi Amy and Conchita

I'm as pleased as the cat that got the cream when I receive your helpful responses.

I wish both of you happy as a peacock.

Thanks

Jupiter
