Can I interest you in a delicious slice of birthday cake?
the Cow Plant (Laganaphyllis Simnovorii) is being brought back to The Sims 3 - as a real Cow Plant, not just the little statue you can buy in the Décor section!
There seems to be a small hitch with purchasing the Cow Plant at this time. Its price is listed at 600 Sim Points, but it cannot be purchased as a stand-alone item. However, it also apparently cannot be purchased as part of any sets. So it's in limbo right now, but I'm sure they will sort that out within a few days.
