By request these are the files used to produce my make www.thingiverse.com/make:400199 of the original adapted to my front doorbell.
Two files for the head sliced to fit my small print area. The third file I created to help it lay against the siding of the house evenly. The "spacer" may need to be adjusted based on your needs.
To connect the head and jaw I placed matching holes for alignment. Use pieces of 1.75mm filament for the alignment "pins".
UPDATED with a remix for a tongue to activate the doorbell https://www.thingiverse.com/thing:3184822
For post I just cleaned up the supports and layered multiple different colors of spray paint. The eyes are pieces of sparkly ribbon.
