In the weeks that followed, Sonic and Merna were making a lot of preparations for their wedding. Preparing the rings, the royal wedding pieces, you name it. One day, Sonic and Merna were sitting in a park in Mertopia, discussing things.

'So, Sonic…Have you considered the sacrifices you're gonna make once you become prince…?' Merna asked.

'Yeah…' Sonic replied. 'It means I can't go on adventures anymore, and that's something I'm really gonna miss: The freedom I had…'

Merna nodded. 'I understand you'll miss that freedom. It's also gonna be harder to stop Eggman.' She said.

Sonic nodded. 'I suppose I could still try and stop Eggman whenever I can…' He said.

'I'm completely fine with that.' Merna said.

'Alright.' Sonic said.

Later that day, Sonic was on land with Tails and Knuckles, discussing the way things are currently going.

'So, are you gonna live with Merna in Mertopia once you're married?' Tails asked.

'Probably. I'll still be coming up here to Port Sunshine sometimes, so don't worry about it.' Sonic said.

'Well, I'm sure gonna miss all the adventures we had, Sonic. Things are probably gonna get pretty quiet up here without you.' Knuckles said.

Sonic nodded. 'Yeah, I bet. I'm gonna miss going on adventures as well.' He said.

Tails was thinking. 'Maybe we could go on one final adventure before you get married?' He suggested.

'That's not a bad idea.' Sonic said. 'I'll ask Merna if it's fine with her.'

Tails and Knuckles nodded and Sonic went to Mertopia to ask Merna for her approval. Merna approved of it and Sonic went back to Port Sunshine.

'And?' Knuckles asked.

'It was fine with her.' Sonic said.

'Great! Then we can go out on an adventure!' Knuckles said.

Sonic nodded and he, Tails and Knuckles left for their adventure. Pretty soon, they were running through a valley.

'This is fun, right, Sonic?' Tails asked.

'Yep! Too bad this is the final adventure!' Sonic replied.

'Make the most out of it then!' Tails replied back.

Sonic nodded and he, Knuckles and Tails kept on running through the valley and into other parts of Mobius. Eventually, they stopped to take a break in the city of Spagonia. Sonic, Knuckles and Tails sat down at a terrace to have a drink and a bite to eat.

'This city is amazing!' Knuckles said, smiling.

'I know, right?' Sonic replied. 'Tails and I love this city.'

Tails nodded. 'I actually helped out at the university of this city.' He explained.

'That's really nice.' Knuckled replied.

'Say, should we stay here for the night?' Tails asked. Sonic and Knuckles looked at each other and nodded.

'Yes, let's do that.' Sonic said.

'Fine by me.' Knuckles said.

Tails nodded and he, Sonic and Knuckles found a hotel to stay at. The next morning, they left and continued their journey.

'Spagonia sure is a beautiful place.' Knuckles said.

'Yes, it is.' Sonic said.

Tails nodded in agreement. 'Yep. We've seen some amazing places throughout the years.' He said.

Sonic, Tails and Knuckles traveled a lot for their final adventure. They basically traveled half the globe before returning to Port Sunshine.

'Man, that final adventure sure was fun, Sonic!' Tails said.

'Yeah, I really enjoyed it.' Knuckles said.

'That's great, guys. I should now go help Merna with more of the wedding preparations.' Sonic said. 'Catch you later!'

Tails and Knuckles nodded as Sonic ran to the ocean, dove in, put on his necklace, turned to his Merhog form and swam to Mertopia. He found Merna in the palace.

'Sweetie, I'm back!' Sonic called out. Merna swam over to him.

'Good, I was starting to worry.' Merna said.

'I can now help with the wedding preparations.' Sonic said.

'Good. Let's get to it.' Merna said.

Sonic nodded and he and Merna got to work.
