Logo idea tweaked and improved

I need a professional to tweak two logo design ideas then finalise the chosen design into primary, secondary, submark and favicon logos in relevant formats.

The business is an online shop that sells children's gifts; toy, book and activity packs. It is called Little Fischy Learning.

I would like to see the images below adjusted as follows;
the first design of the puffer fish without the spikes and party hats.
the second image of the striped fish- add smiles and make them look friendlier.

Could the wave element at the bottom of both designs be made to look like the shape of an open book?
