Colleague Leaving Puns

So a colleague is leaving my work (transfusion medicine lab) to work as an information manager for the organ transplant service. I make cards and I’m trying to think up something punny to write on/in his card and I’ll paint a picture on the front for context. I was thinking like “bloody good luck” or “sorry you’re transplanting”... but less shitty!

Thanks in advance :)

My colleague was leaving the office:

"I need to go to the shop to get some superglue."

Me: "You should definitely get soup."
