I need 2 things: Crafts to do with grass and games to do with bananas. These are for 2 year olds/preschoolers?

Hmmmmmm, this is a hard one.

Well, for the grass craft, if you are okay with growing grass, you could do something like a Chia Pet. Otherwise, you could make nature sculptures, using leaves, grass, flowers, wood chips, fallen bark from trees, etc. You glue them together and voila! A sculpture made out of nature :)

Or if that's too complicated for 2-year olds, you could have them make their own "gardens". Take styrofoam (or some type of foam that you can stick stuff into), glue grass on it, and draw flowers on paper. You cut out the flowers, glue them to either pipe cleaners, chopsticks, or popsicle sticks, and stick the pipe cleaners into the foam.

Bananas... hmmmmmm... thinking...

Well I know that preschoolers (especially girls) like to play with dolls. They could take a marker and draw a face on the banana and they can play with them. The boys could draw on them, making them into either a boat or airplane and play with them.

Or you could have the kids try to stack the bananas like a tower. Lay the bananas on their sides and make a pyramid.

OH! You could line some up on the ground and have the kids jump over the bananas. Or you could do "banana limbo" and use the banana as the limbo stick.

You could do a banana scavenger hunt (but remember where you put them so you don't lose any) and have the kids find one banana each. In the end each kid could get a banana to eat.

Well, that's all I can think of. I hope this helps :)
