While playing as the Cactus, stand on the edge of a Tallnut Barricade or the edge of a wall and activate your drone. Fly beneath where your Cactus is positioned, then ascend to position the Cactus on the flying drone you are controlling. You can now fly up to a high location that is otherwise unreachable. Note: This also can be done with the Engineer with its drone, although not as easily.

Play in Garden Ops mode on the easiest difficulty setting, as the Sunflower. Choose any map you like, though Garden Center works best. Advance through the first wave without using any potted plants at all, until only one zombie remains. Then, quickly plant a Scaredy Shroom plant and lure the zombie over to it when it is scared so it starts to eat it. Now begin healing the Scaredy Shroom using the LB ability, which will quickly generate coins to the tune of about 20,000 per hour, as long as you keep it going. You can even do that while you step away from your console.

Play the "Crash Course" map. Enter the crashed Zomboss ship, then look through the cockpit window to see the Normandy ship from Mass Effect, which is now named "Grass Effect".

Go to the backyard in "Zomboss Estate", and look at the forested section to the left of the graveyard, past the trees that are at the map's boundaries, to see Slender Man.
