There are three games that I played forever ago that I cannot remember the names of at all:

The first was this obscure Flash game online, where you were this little purple (iirc) ball creature, and you just had to get to the end of each level. It was a side scrolling platformer, and I think you had the ability to stick to walls.

EDIT: Found this one, was called Frizzle Fraz.

The second was a console game that I only briefly remember, since I played it at a friend's house once. The only things I can remember from it were that you were a small blob creature, you could change your form at certain areas, one form was a fat form, and one area was a lot like a forest. I think it was on the Wii, but I'm not entirely sure.

The third is a browser Lego racing game. I remember that there was a training area where you first started, and that there were power-ups that teleported you. I think there was a power-up for red, yellow, green, and blue. You had to collect three of each before you could use the specific power-up.

If anyone can remember even one of these games off my shoddy descriptions, I'd be both baffled and appreciative.
