For this puzzle (and others like it), the rebus tool should be used as each cell can have 1 to 3 letters. The numbers in the square brackets tell you how many letters long each entry is, as an extra hint.
These puzzles give me a headache trying to make them, but its really satisfying when the pieces all fit together. Some of these words/phrases are a little ridiculous, I will admit... but I'm just making these for fun, so why not!
