Ok to get 106 I sure it is 106 but it might be 105. Start a new game and enter your name in as wombat then go into the game. This only works on xbox I'm afraid and you have all the powers and everything.
To get the 5 secret gems, you must get the 5 coloured gems and there is one secret gem in each of the 5 levels that have a secret gem. The coloured gems activate coloured gems platforms which take you to a secret gem and the platforms on each of the five levels are different colours and he is the levels that have the coloured gem platforms
