Sally Acorn was a lovely chipmunk with a glossy, brown coat. She was in a dilemma. Sonic the Hedgehog's birthday was coming up and she didn't know what to get him. Sonic was not just any hedgehog; he was a blue, extraordinarily fast one, and also her boyfriend.

She was pondering what would be the best gift for him. Sonic had everything he needed, and he was not materialistic. Getting a birthday present for Sonic was not an easy task.

While she was occupied with her thoughts, she noticed Amy Rose. Amy was a pretty, pink hedgehog, who was also a good friend of Sonic. She was relaxing on the beach, looking carefree in a cute bikini.

This sparked an idea in Sally's mind. She decided to give Sonic a surprise by delivering Amy to him as a birthday present. She knew Sonic would be thrilled by this unexpected gift.

Sally cautiously approached Amy and unexpectedly tackled her. She quickly took out duct tape from her bag, tied Amy up, and covered her mouth to prevent her from screaming.

With Amy all bundled up, Sally started her journey towards Sonic's house. She was excited and nervous about his reaction. Would he be surprised? Would he be pleased?

On reaching Sonic's house, she put Amy in a giant gift box outside the door. She rang Sonic's doorbell and hid, waiting for his reaction. She could hardly contain her excitement.

Sonic was inside, in the middle of his morning routine. Hearing the doorbell, he went to answer it. He was surprised to see a giant gift box outside his door.

Out of curiosity, Sonic opened the gift box. And there was Amy, tied up and looking surprised! Sonic was startled for a moment, but quickly recognized it as a playful act.

He was overjoyed to see Amy! He untied her and thanked her for the surprise. Amy, still recovering from the shock, smiled and wished him a happy birthday.

Just then, Sally stepped out from her hiding place. Sonic turned around and was even more delighted to see his girlfriend. He hugged and kissed her, thanking her for the wonderful surprise.

Sally, glad to see Sonic's happiness, asked him what they should do next. Sonic thought for a moment and then came up with an idea that would make the day even more enjoyable.

Sonic suggested that they all hang out at his place for the day. He had the perfect idea for a relaxed, fun day. Amy was relieved and agreed to stay for the day.

The three friends made themselves comfortable on Sonic's plush couch. Sonic and Sally were hugging and cuddling, their hearts filled with joy and contentment.

To make the day even more special, Sonic asked Amy if she could wear the coconut bra that he had randomly bought on his last beach vacation. Amy was surprised but agreed to Sonic's request.

Amy donned the coconut bra and a grass skirt, transforming into a tropical island dancer. The sight was amusing and all three of them burst into laughter.

Amy started dancing to some imaginary tropical tunes, adding to the fun of the day. Sonic and Sally were thoroughly entertained by her dance moves and joined in the laughter.

There they were, Sonic the Hedgehog, Sally Acorn the chipmunk, and Amy Rose the hedgehog, creating unforgettable memories on Sonic's birthday.

Sonic's birthday turned out to be more fun than he had ever imagined. It was filled with surprise, laughter, and good company.

Sonic thanked Sally for making his birthday so special. Sally was delighted that her idea worked out so well. It was a memorable day for Sonic, Sally, and Amy.
