Boost:
While you are running press the attack button to speed up a short time. Only works on the ground or in water.
Infinite Lums in "Hi-Ho Moskito":
Suck the bombs in when the bird attacks you. But don't shoot the bird. Shoot against the wall on the top. The bombs will respawn again and again. With every bomb you sucked in you'll get two Lums.
edit:
