R's Really Rare Rose

When Alphablock R leaves Alphablock W to look at her rose, the plant wilts. It needs water. W makes the dry well WET but cannot reach the rose because the bucket is on a rope. He transfers the water into a CAN but there's a leak. A CUP full of water proves too big for W to handle. He manages to make it TIP. Swamped, the rose wilts again. HOT sunshine saves the day, until W's friends accidentally give the yellow rose a red DOT that spreads over the entire flower. Fortunately, R is delighted.
