Ellie's Unexpected Surprise

Ellie's Unexpected Surprise is the fourth episode of Dave the Dog Does.

Plot
Dave and his friends celebrate Ellie's third birthday, but must get ready before Ellie wakes up.

Story
At the beginning of the episode, Dave is seen putting Ellie to bed. He then sees Betsy and talks to her about the big party happening tomorrow. Soon, Dave gets everyone and stacks them in a large pile, while Betsy gets Bryan to help. Pterry is then awoke and asks what is happening, and who will do what. Everyone gets prepared, as Pterry tries to pick up Wiggles. Blue is then seen talking about how he's never been downstairs before.

Dave and Princess are downstairs, talking about decorating. Dave walks behind the sofa and finds a party blower made out of paper. Soon, Dave and Princess are asking Bryan and Betsy to help with their birthday machines they've been working on. Dave then tries to poke a hole through the machine to let the balloons come out. He tries and tries but no matter how hard he does it, he fails. Princess asks Dave for glue and scissors, yet they don't have any.

The bunting is all up. The first birthday machine is built, version 1.9. It tries to blow up a balloon, but it deflates, with Princess saying the deflation of the balloon makes it look like a pear. Dave soon returns to see how it works, yet it doesn't work. Soon, Princess has built the second machine, version 2.0. Princess gives a "green grape" balloon to the first machine, causing it to fail.

Meanwhile, with Hopsterz and Pterry, they decide to get a chocolate cake. They come across one with seven blue flags included. They are soon seen putting the candles on the cake, talking about if they want to use candles. They don't, as Pterry doesn't want anything getting burnt.

Soon, Ellie wakes up, and walks down the stairs to find a balloon and everyone there to celebrate. They suggest on eating some cake, as Dave talks about the party decorations.
