This is how Jemaine plays it live. It's basically the same riff over and over with a
finish:

G|-----------|-----------|-----------|-----------|
D|-----------|-----------|-----------|------2----|
A|-----------|-----------|-----------|-3---------|
E|-5-5h7p5-5-|-7-7h8p7-0-|-1-1h2p1-1-|----5----4-|

G|-----------|-----------|-----------|-----------|
D|-----------|-----------|-----------|-----------|
A|-----------|-----------|-----------|-3---------|
E|-5-5h7p5-5-|-7-7h8p7-0-|-1-1h2p1-1-|------4----|

G|-----------|-----------|-----------|-----------|
D|-----------|-----------|-----------|-2---2-----|
A|-----------|-----------|-----------|-----------|
E|-5-5h7p5-5-|-7-7h8p7-0-|-1-1h2p1-1-|--4-4--4-4-|

And repeat.

During some parts of the song like when Jemaine (the "Hiphopopotamus") is singing, the 
line simplifies to this:

G|---------|---------|---------|---------|
D|---------|---------|---------|---------|
A|---------|---------|---------|---------|
E|-5-----5-|-7-----0-|-1-----1-|-0-----0-|

You pretty much just omit the pull-off thing from the main riff, and the different endings.


Sometimes this part simplifies even more so you only play the first note in each section:

G|---------|---------|---------|---------|
D|---------|---------|---------|---------|
A|---------|---------|---------|---------|
E|-5-------|-7-------|-1-------|-0-------|
