Who remembers this 1980s/90s cartoon?
Set under the sea.
About two fish detectives.
I used to watch this every Sunday morning on channel 4.

Enough with this banter.

This is the tune.

Bass bit;
G|--------------------|--------------------|
D|-----------0-----0--|-----------2-----2--|
A|-0---3---3----3-----|-0---3---5----5-----|
E|--------------------|--------------------|

During the verse, after each line, play this bit.
E|---------|
B|---1--3--|
G|-2-------|
D|---------|
A|---------|
E|---------|

Chorus;
E|--------------|---------------------|--------------|
B|--------1--3--|------1-----1--3--1--|--------1--3--|
G|-2--2---------|-2-2-----2-----------|-2--2---------|
D|--------------|---------------------|--------------|
A|--------------|---------------------|--------------|
E|--------------|---------------------|--------------|

E|-------------------|
B|------1------------|
G|-2-2-----2---------|
D|------------0--2-2-|
A|-------------------|
E|-------------------|


Finish with a simple Am chord.
