Inside Clank was a level which involved Ratchet using the Shrink Ray to go inside Clank. Ratchet went inside him because the Technomites invaded Clank when he found out the coordinates from Luna's 'dead body'. It was a very interesting level as you got to see the inside Clank. There were lots of enemies inside which took a fair amount of ammo to take down. When all the enemies died, Clank's security backup in his memory bank turned on the anti-virus program to prevent future breakouts which meant Ratchet had to escape or else it would have hunted him down.
