Traversing the expanding universe with his companion teddy bear Sarah, spaceman Alan explores the depths of the cosmos. One day while visiting home, Alan and Sarah saw a periscope peering out of the water. Alan and Sarah investigated and discovered scuba man Dan and octopus Tina. The foursome’s mutual love of exploration immediately united them in friendship. They take turns exploring all corners of the expanding universe in Alan’s turbo powered rocket ship and investigating the depths of the ocean throughout time in Dan’s time traveling submarine. One day they might be underwater in the Mesozoic Era watching Ichthyosaurs swim and play and on the next day in outer space watching a star implode. No matter where they are in time and space they have fun because they are together.
