Grab him with tendrils

As John extended his arm a vine covered in razor sharp thorns wrapped around it. "Aaaarrg!" He yelled in agony. "What the fuck!?"

Petra just smiled,"Ivy!" she called.

A red headed woman and a green dress came running, "Yes, mistress," she said as she curtsied to her boss.

"Make sure we have a few accessories for our new client."

John looked terrified. Another vine grabbed his other arm as he tried to grab at Petra or the other woman.
