While playing 'de Blob 2' I was made aware of some codes which are very useful when going for the 'Keepin' it real' trophy.
These codes do not effect the unlocking of any trophies and can be used at anytime, I have confirmed this myself.
For all of these codes you need to enter them while active within a level and NOT from the main or pause menus.
Time Bonus -> Hold down

+

and then select

,

,

,

This will add 10 minutes to your time clock up to a maximum of 90 minutes.
Extra Life -> Hold down

+

and then select

,

,

,

This will give you an extra life (red item).
Extra Armor -> Hold down

+

and then select

,

,

,

This will give you an armor pickup (blue shield)
Finally, another code that I found extremely helpful is holding down

,

and

then tapping 3 times either

or

. This will allow you to freely cycle through the colors and even clear off the Black Ink without having to get to a water source. It does NOT solve fire or electric shock, but it makes things so much easier for completing difficult levels.
