memenuhi also can. But, mengisi is better because they just fill their bags with bananas and peanuts. They do not fill their bags with it until full because memenuhi more to full something because 'penuh' means full.
The options are there but you need to scroll down but there is no option to scroll. I can just see the tops of 2 tabs which are below the line but they have the words. I have reported.
I just did the refresher on plurals - and had almost this exact phrase with 'pisang-pisang' ... but not now... Soooo - when do you use the plural form?????
Use the plural form when you would otherwise assume the noun is singular. If you read "Saya mencintai kucing saya", (I love my cat[s]) you would think of only one cat. But with "Saya mencintai kucing-kucing saya", (I love my cats) there is more than one cat.
