Nightmare Fuel: The Blob
The '80s remake.
Many of the deaths are quite terrifying. Good examples are Paul whose eyes have just dissolved and his eyesockets bleeds and his face looks like the Scream mask and Kevin's friend who pops out of the water, half melted and screaming.
The woman from the diner runs out after witnessing the Blob kill one of her workers. She goes to a phone booth in an attempt to call the sheriff for help. All this time, the Blob is surrounding the phone booth...
The Kitten. Anyone who saw Beware! The Blob knows this damn well.
