My theory on the smaller life form seen at the end of found footage 1

My theory is that this smaller life form is a probe like seen in 2005 war of the worlds where in this case bacteria or the life form did mitosis and transfers his consciousness into what I’m calling the probe so move around faster cause he’s most likely slow when walking cause he’s big at full size and when Kane turned around the probe saw him so bacteria reabsorbs this chunk to become full size again so he can finally kill Kane without Kane knowing he was already spotted while Kane was distracted by the hole and my theory for found footage 2 life form is that it’s the same lifeform but after consuming Kane he integrated pieces of Kane into itself so it become a better hunter hence why his head protrudes more so he can easily dispatch prey with his mouth instead of hands and also so he can eat faster cause he would be able to consume larger chunks of flesh
