I got something interesting for my birthday today.
It seems strange to me that someone is publishing books like this. Going by that "look for all" blurb on the back cover, this must be only one of several such Pufnstuf activity books. Printed by Modern Publishing, which is apparently licensed to print such books featuring a lot of different kid & cartoon characters. This was found in one of those big "odd stuff for a dollar" boxes at Dollar General. This book doesn't seem to be in their current catalog.
