Been playing around with fitting the animation to the sound and basically, something has got to go. Either I leave it as it is, cut the beginning so that the sound starts sooner or take out the extra 'A BOX!' line as I can't really fit everything in.
I made a video of options to show Team RRR for their opinions.
Both thought option 3 (take out the extra line) was the best one. So that's what I will do!
