Now I really need to see the magic mallet being used on her. Both for hotness that is a cute girl in a school swimsuit but also to see her own Tokonatsu for not jumping dat Fubooty, she'd also teach Lezadmiral to keep her hands to herself.
I copied the tags that t34/38 added. Removing as it doesn't reflect a particular scene from that game, and replacing with style_parody instead due to the Soejima styling.
The last note indicates that her buddies ate it when she wasn't looking.
That's a parody of the usual boilerplate disclaimer on cooking shows. In a comedic context it almost always implies that yes, the food is being wasted.
Plus if her buddies snitched it, she wouldn't regret it the next day (this implies she didn't even notice until the next day, whether the banana was eaten or not). Heck, she'll be thankful.
Minutes or hours later, maybe. Certainly not a whole day.

The Fairies' Everyday LifeArrr!I'll eat it, but let's just leave it as decoration for a while.The next day, she regretted this decision.It'd be a waste.
※The fairies later enjoyed it with gusto.
Parody of standard "no prepared food was wasted" reassurance boilerplate from cooking shows and such.
