Hints:

Ah, that's better. Water always works.
Hic! Oh...
Oh, dear. Hello, everybody.
Sorry I'm late.
Have I missed anything? I guess you don't bother to knock any more.
Thank goodness! Owl is here. He'll know what to do.
About what?
Water won't stop my hic, hiccups.
Well now, let me think.
Water is a good idea but he must hold his breath too.
Hic, how can I, hic, hold my breath too? Hic!
Well you could try. Trying never hurt anybody.
For how long?
For as long as it takes.
