This translation is a game. I'm looking for words sound like the followings:
"Eleven hal úszik a víz alatt" as:
"Alive fish swims the water under"
So when fish is not like "hal", then it could be changed to "whale", for that is more similar and the meaning is not far from the original.
So please write a translation that has a similar meaning and even more similar sounds, as much as possible.

I need to wish somebody a nice day, like a felicitation. I really want him/her to feel that I wish him/her the best.
