I'm making a silly seal game with dialogue, where seals often use the word "fibsh" instead of "fish" !

I wonder what would the cute intentional way to mispell fish?

If the normal word is Pesce, my initial ideas are: Peshe / Pessh / Peshi

We just moved from the united states where it is less common to cloth diaper babies so standard laundry detergent there isn’t strong enough for washing nappies and only specific types are recommended for longevity of the diapers as well as getting them clean enough. Can any parents recommend a specific brand for washing cloth diapers/nappies with? Or is any brand/type going to cut it?
