DRAKE! is a meme video by Cajansoar. The video uses a clip from "This is America" by Donald Glover. Wombo is a reference to the episode "Mermaid Man and Barnacle Boy IV" from the TV show, "SpongeBob SquarePants".
The video shows Drake walking around in a Minecraft world. After walking for a bit, he gets shot by Donald Glover. Glover then walks off.
