Really easy, dunno why no one had put this in E cause thats how it is in the song. Anyway

Verse:

E (022100@1)             G#m (133111@4)       
Sometimes I get my head in a dilly
A (x02220@1)             F#mFeeling (244222@1)so lost ticking you off
ENow (022100@1)boy, You know me well
G#mSaid, (133111@4)I'm that kinda feeling
AThat (x02220@1)kind of soft
F#mThat (244222@1)kind of silly
EBut (022100@1)when I'm in doubt
G#mI (133111@4)open my mouth
AAnd (x02220@1)words come out,
F#mWords (244222@1)come out like

Chorus:

C#m (x13321@4)                     ABaby (x02220@1)there's a shark in the water
E (022100@1)                            
There's something underneath my bed
BOh, (x2444x@1)please believe I said
C#m (x13321@4)                       ABaby (x02220@1)there's a shark in the water
E (022100@1)                   
I caught them barking at the moon
BBetter (x2444x@1)be soon

Verse:

High in the sky
The song that I'm singing
A sweet little lie
A cry wolf cry
Rather have you lie
So that's why I'm bringing
Some tricks up my sleeve
For noticing me
Wuldn't cause you any harm
I just want you in my arms
I can't help
I can't help myself

Chorus:
Baby there's a shark in the water
There's something underneath my bed
Oh, please believe I said
Baby there's ashark (x02210@1)in the water                     
I caught them barking at the moon
Better be soon

Better be soon

Bridge: same chords as chorus

Right is right, Rules are rules
This is more like april fools
I'm just winding you up, oh
Jack be nimble, Jack be quick
Please don't make too much of it
It aint that serious
Oh ohh ohhhh

Chorus:

Baby there's a shark in the water
There's something underneath my bed
Oh, please believe I said
Baby there's ashark (x02210@1)in the water                    
I caught them barking at the moon
You'd better get here soon

Baby there's a shark in the water
Baby there's a shark in the water
I caught them barking at the moon
Better be soon
