Fear of the Cactus (Kactosophobia)

Figaro is looking for the appropriate spot to plant a gorgeous tulip.
He decides that a hideous cactus needs to go. Rivet has to do the dirty work, due to Figaro's cactus phobia. Not without reason, as the cactus is actually alive and swears revenge!
When Figaro is gone, the vindictive cactus reclaims its rightful place in the garden, to the detriment of the tulip. Figaro discovers the disheveled tulip. Unaware of the cactus' actions, Figaro is convinced that Rivet is responsible.
Can Rivet prove his innocence? Will the Cactus be forced to reveal its true colours?
It ends in a Mexican standoff – who will win? The good, the Bad or the Ugly?
