I got this one in the first secret stage in Mallrow Street (third area available after the Introductory Road and the Easy Street). Just to the right to the bus station, you'll see two No Parking signs and behind them, an alley with a star sign. When you go to this place, you will enter one of these "special stages" that can be found in some Sonic games.
The difference here is that you use LT and RT instead of Left and Right to move, but nothing very tricky. There are three ways to fail:
- by not getting enough piles of cans in each zone (respectively 20,, 70 and 110 for a possible total of 35,90 and 135) ;
- by running out of time;
- by hitting a mine.
Just take your time to avoid the mines, don't bother getting every can pile if you feel that you are late. It should not take you more than two or three tries.
If you make it to the end of the third zone, you are bound to get the achievement!
