For the "I like turtles" badge (3 million feet in one shot) without the 5 hour badge which gives +100% Cannon Power...
1. Have everything upgraded (Tank, Golden Gun, Missile)
2. Have Around 30-40 Nukes (Just In Case) And A Chestbomb for a one time protection from spikes.
3. Fire at a 45 degree angle
4. Only fire at your turtle when he is slowed down to about 40-50% speed, one shot from the golden gun is more than strong enough to put you back to top speed for a good 150,000 feet at least. Letting your turtle slow down before you shoot also gives you a better chance of getting a ammo pickup.
5. Only resort to Nukes if your unlucky and run out of ammo and have not gotten any ammo pick ups.
***If you get one ammo pickup, your basically guaranteed to make 3 million feet. I got 4.5 million feet first try with this method.
