The Cow Plant looks like a bit of a nod to the Plants Vs Zombies series (also published by Electronic Arts). To unlock this bovine greenery, you'll first need to head over to Desert Bloom Park in Oasis Springs. Once you reach there, head over to the mineshaft door, but don't actually enter it. Near the doorway is a small pond, which you can fish in. Stick with it, and you'll eventually 'catch' a Cow Plant Berry. Plant the berry in your lot, and wait a few days. It takes a while, but you'll eventually be left with a glorious, healthy Cow Plan, complete with udders on its chin. Be careful though - it's very possible to be swallowed whole by one of the fully grown Cow Plants if you're not careful! What's your favourite Sims 4 secret? Are there any we missed?
