O sees some drops of water falling from the sky. He sees it's starting to rain. He sees W, E, and T running in the rain. R, U, and N are running as well. U's umbrella blows away and O catches it. He sees F, U, and N jumping in puddles. S flies in and hold hands with U and N.
A sun appears, as well as a colorful rainbow. O walks through the rainbow and bumps into G. They've been color-changed as they walk through the rainbow. Then they walk on the rainbow as they sing the colors. At the end of the rainbow they see a pot of gold on the other side of a rainbow-colored river. They come down, but they don't know what to use. Suddenly, B, C, D, F, H, J, and L slide down from the rainbow.
How can they reach the gold?
BOG - B, O and G are in a bog.
COG - C rides on a cog, but it doesn't reach the gold.
DOG - A dog appears. After turning rainbow-colored after jumping into the river, it instead digs for a bone.
FOG - F, O, and G are in a fog.
HOG - A hog refuses to help.
JOG - J, O, and G go jogging.
LOG (star word) - A log appears to make as a bridge for the Alphablocks to cross the river. G, O,L, and D, cross the log to get to the other side.
They come to the gold, but O sees it too useless. They dump out the gold and use the pot as a boat to sail across the rainbow river. And all the Alphablocks sing a cheerful song once again.
