Silent E

Silent E is the villain protagonist of the animated segments of the same name, which was derived from the live-action "Vowel Boot Camp" skits.

Silent E is a criminal because, as he adds an "e" at the end of a word with only a short vowel and ending with a consonant, he turns whatever the original word matches into that which the final word matches: he turns a cub into a cube, a tub into a tube, a twin into twine, and a can into a cane.

When arrested, he is told that he has the right to remain silent.
