"What kind of riddle?" he asked.

(I can't think of one...)
"It's a number-based one I'll tell ya that much." I said
"It says ' How many 9's are there between 1 and 100?', 'What is the difference between a new penny and an old quarter?' and ' What number can you subtract half from to obtain a result that is zero?'" I translated

He didn't really know how to respond to that.
(And neither do I. xD)

(3 riddles for the answer. It's a button combination of how many times you gotta press a certain button.)
"Okay so the 1st Riddle's awnser is 20." I stated writing it down on a piece of paper

(For the third, I was gonna say 0.1, but half would be 0.05. Only thing I can think of is 0. :/)
Tails thought about the second one.

"24 cents." I said for the 2nd riddle writing down the number and then staring at the 3rd riddle "8. If you cut 8 in half you technecially have 2 0s." I stated writing it down (The actual answer is 8 btw for the 3rd one)

(Oh, so you meant it literally. xD I wasn't taking it literally.)
Tails thought for a minute.
"So we just have to push that one 20 times, that one 24, and that last one 8?" he theorized.

"There's 5 buttons, You push one 2 times, the second is to be ignored, the 3rd twice again, the 4th 4 times and the 5th 8 times." I said

"That makes sense then." he replied.

"Lets do it" I said going to put in the combination

Tails punched in the first two, and let Blue have a turn with the last two.

I punched in the last two and the machine that looked like a clock started to turn and move as well as glow and light up the entire area

"Wow! What's this?" he exclaimed.
(I bet the rest are like: "Where the fudge are they!?"

"I think this is where the Adamant Orb is." I said smiling, The machine was still moving before opening like the Time Gate in Skyward Sword

He slowly walked inside.
