Prologue:

The Hero Team (still unofficial name) were all putting a table near the beach, except Shadow who was just sitting in a corner, and tails who went to bring sonic.

"Everything is read!" said Amy. "we only have to wait for Tails and sonic, DON'T TOUCH ANYTHING KNUCKLES!"

"but… pretty!" said knuckles.

"no! bad knuckles! You'll have some later!" said amy.

"okay! Stop talking to me like an Animal!" said knuckles and went to sit beside shadow.

"you sure you don't want me to put any traps Amy?" asked Sticks.

"we'll be fine sticks!" said amy. "and thanks for helping shadow."

"hey you're lucky that I even showed up." Said shadow.

"oh yes, how lucky we are…" said Amy sarcastically.

A few seconds later, Tails came running.

"He is coming guys!" said tails.

Amy and Tails hid under the table, Sticks jumped on top of a nearby Palm tree, shadow teleported and knuckles hid behind a small rock.

"hey guys, what's going on?"

Sonic came and looked around, and found a cake on the table with the number 20 written on it.

Then everyone got out of there hiding place and yelled:

"SURPRISE!"

Then shadow teleported back with a bit of delay.

"what they said." He said.

"Happy Twenty years anniversary sonic!" said everyone, shadow with a slight monotone voice.

"guys! You shouldn't have!" said sonic.

Sonic cut the cake, And Amy had to stop knuckles from eating it all. While tails went to get the gifts.

"Open mine first! Try to guess witch one it is!" said knuckles.

"the red one?" said sonic.

"… it could have been any other one…" said knuckles.

Sonic opened the red gift and found inside… a red gift.

"It's a birthday box!" said knuckles. "you can put anything in it!"

"…thanks…" said Sonic awkwardly.

He then took a pink box.

"That's mine!" said amy.

He opened it and found a comic a book.

"I know you collect those." Said amy.

"It's the Action Comics #1 !" said sonic, "one of the rarest comics ever! How did you get it?"

"I am an archeologist, finding rare stuff is my bread and butter" said Amy smiling.

He then went to The yellow box, which he assumed was Tails's. and he found a pair of new shoes.

"I made a few upgrades on this shoes, you can now use the lights speed dash just like shadow." Said tails.

"awesome! You hear that shadow!" said sonic.

"can you teleport? No? I thought so." Said shadow.

"of course I imagine you didn't bring me anything, I am lucky that you just showed up." Said sonic.

"actually…" started tails.

He went back to the Shack and got out with a large box wraped in black.

"wow I didn't expect…" started sonic before getting cut by shadow.

"Just open it!"

And he did.

"Its… it's my guitar!" said sonic. "but how? It got destroyed…"

"Fixed it; wasn't that hard." Lied shadow.

"i… don't know what to say…" started sonic.

"then shut up." Said shadow crossing his arms.

"sorry I didn't get you any gift," said sticks. "I was gonna get you the coolest gift ever, but Amy said I should just bake the cake."

"what gift was that?" asked shadow.

She answered in his ear.

"That's the most awesome birthday gift EVER!" said shadow.

"there is still one gift." Said tails.

"we waiting long for this." Said sonic.

"…Maybe you should go open it on your own, it's your gift…" said tails.

"no way, I wouldn't late you miss it little bro, common let's go get it!" said sonic.

They both went back to the beach shack.

"what are they talking about?" Asked Sticks.

"Uncle Chuck's gift." Answered shadow.

In the Shack:

Sonic got the blue present, With Open only at your 20th birthday- uncle chuck on it.

"you're ready Tails?" asked sonic.

"yeah, do it!" said tails.

And he opened it.
