Now S can’t make her ‘s’ sound any more. Her mischievous letter doesn’t want to be caught and enjoys making her friends SLIP and SKID in the snow. Alphablock O has an idea. T challenges the letter S to a race up the hill. The other letters arrive on the TOP first and then jump out to grab the ‘s’ to make STOP. Now, they can put it back in the right SPOT in S’s dome.
