Check out our walkthrough video for Ragnahog level 19 below. We use 3 birds for 155350 and 3 stars.
Send chuck fairly high and activate such that he strikes the ice boulder on the far right. Boulder and snow blocks fall, taking out everything to the far right. Send little Red straight ahead to hit the beam above the cage. Most everything falls by now. Stella follows Red into the middle, sending most of what is left down into the pit. As we watch the points roll up, we see that we never even hit the stove!
