Impossible Spleef Achievements?

[Think Games]

Hi there! Today I gave myself a goal of collecting all the arcade achievements, and when I got to the spleef ones I got stumped by how impossible two were. The ones that I find to be impossible are the don't break and blocks on Pizza, or spleef. I do not understand how to do this as you would starve within 1 minute if you didn't break any blocks in those games. Is there a secret or was this not thought of during the achievement planning.

Please Help!
