When Inui Toko-chan was taking in marshmallows it came out that her size is seetie[sic] (how big they are) so I looked up the size and drew it.
The larger varieties of seeties[sic] seem to be about the size of a handball so I got excited.

Made some minor edits to the Toko-chan Sweetie picture....
When I looked it up again, it wasn't "seetie" but "sweetie", and I thought under "sweetie" there was another kind called "oroblanco", or that "sweeties = oroblanco" and there was just one kind, however "Israeli kind = sweetie" and "American kind = oroblanco", and as for the size, "small ones = iron throwing ball" ~~ "large ones = handball"...
I learned a lot.
I guess my desire to learn or curiosity was boosted by desire...
Up until this point I hadn't looked much into fruit.
To be honest I was more looking for the size of the fruit than the name.
