Recommend a good morphing program?

I thought it might be fun to morph these four pictures:

Any suggestions on programs you’ve used?

As a composite single pic, or as a movie that morphs from one to the next to the next etc?

(The one I use is simply called “Morph”)

I have nothing useful to add but I just had so say what a cutie she is.

My youngest son is 3. Is your daughter dating yet?

A movie that morphs pic 1 into 2 into 3 ending with 4.

My daughter will not be allowed to date. She is going to be a nun (polishing his shotgun).
