All you do is watch them change costume... Pico changes costumes every picosecond (0.0000000000001 of a second). Nano changes costume every nanosecond (0.0000000001 of a second). Giga changes costume every gigasecond (1000000000 seconds). Tera changes costume every terasecond (1000000000000 seconds). They all change x and y by their second also.
I noticed the names so there.
