Can be easily obtained on level 19 of the ‘Garden Party’ levels. Start off by grabbing the shovel located towards the centre of the level and use it on one of the dig spots with the three sticks poking out. Next you will need to grab the tall potted cacti plant and place it within the hole you just dug. Once the plant is placed, the rest is pretty self explanatory; just continue walking into it until your achievement unlocks.
