Not only would you have to lug around Piranha Plant anywhere that you would want to go on a date, but this plant monster will more than likely bite your head off or possibly spit poisonous purple gloop at you while you’re just trying to give it a little goodnight kiss.
Imagine being in a movie theatre watching a romantic film and then all of a sudden, Piranha Plant spits out a metal ball at the projection screen, tearing a gigantic hole in it.
That would just be absolutely embarrassing and then people will stare at you wondering why you brought a damn plant as a date for Valentine’s Day. You can explain all you want but they’ll still think of you as a freak.
If you wanted to take Piranha Plant out on a date, I would recommend taking it out to the dump.
