When Alphablocks E and S offer to help with his party, Alphablock Y says, YES. Each time he has a new idea, Y realises that he needs more than one of each thing. One party HAT, one CUP and one BUN won't be enough. Fortunately, S knows how to make plurals: 'When you need more than one, add an S and see the fun!' Soon, they have HATS, CUPS and BUNS galore. But when they need a second BUS to pick up the guests, adding an S doesn't work. This time, E can help too – BUSES. Is the party a success? Yes! 

When Alphablock I's pen runs out of ink, Alphablocks N and K team up to make NK. Alphablock I makes more INK but causes a flood and needs to clear it up. Turning the ink PINK doesn't help. She contains it in a SINK but finds herself trapped in there with her friends. They turn the sink into an ice RINK. Everyone slips around, until Alphablock I has a THINK and comes up with the idea of ice skates. Now they can enjoy skating on the pink ice, and Alphablock I can THANK her friends for their help.
