This is likely because in the song from which this meme is riffing of of, Africa is sung with an elongated “a” like “aaaafrica”

Edit: Africa by Toto, 1:20 seconds in

I assumed because Africa doesn't exist on Toril.

It's a reference to Toto's song "Africa", and in the line "I bless the rains down in Africa" the "A" gets extended a lot.

They did it twice so it seems intentional. Beats me though.

D&D campaign changing the names of real places to keep the fantasy setting?

Anyone else read that as Jackie Daytona?
