An envelope with powder and a vague message prompted hazardous materials experts to respond to Clover Park Technical College on Tuesday.
The powder, left with the envelope on a student’s vehicle, turned out to be instant pudding mix.
“I believe it was chocolate,” West Pierce Fire & Rescue spokeswoman Jenny Weekes said.
The message, which Weekes believed was written on the envelope, stated something to the effect of: “Thank you for your service,” she said.

Emergency crews from multiple agencies arrived about 1:30 p.m. They closed one of the campus buildings as they investigated, because a campus security worker had taken the envelope inside.
Lakewood police made a report of the incident, spokesman Chris Lawler said, but had no suspect information.
