Notes:

From an anthology comic series publish by Mirage (As in, the very same who made the original black and white TMNT comics)

Yes, this is an actual officially licensed TMNT product okay'd by the creators.

For context, Splinter is about to give the turtles shots to protect them from a sickness known as "Shell Fungus" which is fatal for turtles. But Splinter's expression in the final frame telling them to "bend over" is rather disturbing…
