It was Sonic's birthday, and all three -- Classic, Modern and Grandboom, as they shared the same birthday -- were celebrating to their hearts' content. They had invited all of their friends to a huge party. By the end of the day, the party was over; gifts were exchanged, the cake had been eaten and the guests left one by one - however, Grandboom had another surprise in store.
Grandboom had gone to the local bakery and ordered a custom birthday cake for after the celebrations; something special for just the three hedgehogs. He also wanted to get some extra presents to surprise the Sonics. Of course, he didn't tell them about any of this -- but little did he know that the Sonics were planning to surprise him as well.
To show their appreciation, Classic and Modern were going to bake some birthday cupcakes for Grandboom. "I'm just going out to pick up a few things, so I should be back in half an hour," Grandboom announced. This was the perfect opportunity to work on their surprise!
