Four friends are excited to play together, but each one has a different idea of what they should do. Period (the serious one) believes they should go to the library. Question Mark (the confused one) wonders whether they can chase butterflies.or was it whether butter flies? Comma (the hungry one) just runs on and on about food. Exclamation Point (the crazy one) wants to go on lots of extreme adventures! That are dangerous! And exciting! With everyone only thinking about themselves, their friendship almost comes to a full stop, until a strange and unexpected newcomer shows them how much more fun life can be when everyone works together...
