Alphablocks Season 6 Episode 1 Party Party Episode Title: Party Party Episode Description: 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!
