Like a Werewolf. Transforms at the sight of moon. Does covering eyes make them transform back?

When an anime characters does this smiling expression ^_^ does it count as closing eyes?

If it does, then Carrot did that in her sulong form and didn't change back, meaning there's no need to be within contact with the moon to stay in sulong form.

But even if it doesn't mean eyes are closed, carrot focused on the enemy forces rather than the moon.

I think they only need to be in the exposure of a full moon (and trigger transform by looking directly at it)

It doesn't count.

They squint slightly when they close eyes.

All they need is the moonlight to shine on them.

I am not really sure..but if i am not mistaking, carrot were putting a cloth to cover her eyes after she returned to her normal form..also Bigmom kids were trying to close pekoms eyes too whe he was in sulong form..but lemme reread the chapters first

In conclusion,,they need to look at the moon once in a while to stay in sulong form

No they just need to see it once. The moonlight itself keeps them in the form.

Carrot and Pekoms both only looked at the Moon once and blinked at least once so I'm pretty sure that its just as long as they look at the moon once because normally according to Jinbe, most of the time they can't control their sulong form and die from exhustion so I think its as long as they have the energy to keep the form on.
