Heartwarming / Man Who Speaks In Hands

• Just how much Gaster loves his sons, really. Every single time they're brought up, he talks about how proud he is of them and how brave and responsible they are.
• The Gaster Blasters are family pets. And they're pretty adorable!
• Gaster enlists Toriel's help.
• Getting a hug.
• Thanks to an asker, Gaster gets free of the void. He's literally jumping for joy as he runs off.
  • And then he reunites with his sons, Sans and Papyrus, and many tears are shed.
• Gaster is visibly downhearted after being returned to the void. And so, an asker drops a box of nice cream into the void for him.
  • This leads to an avalanche of packages—a baby blaster, a sweater, a box of cookies, cinnamon buns, journals, colouring books, sharpies, hot chocolate, blankets, a laptop, mittens, kittens, hot dogs, spaghetti, six turtlenecks, a plush Mettaton, a whole bed—burying poor Gaster underneath the pile.
    Gaster: GREAT GOOGLY MOOGLY THERE'S SO MANY OF THEM!
• Gaster pulls a Heroic Sacrifice against Flowey in the Neutral arc. Fortunately, Frisk's right there.
• Gaster's nickname for Papyrus is 'little noodle'.
• During the Pacifist Arc, everyone is turned into Lost Souls except for Asriel, Frisk, and Lucida. And while Frisk starts Saving the Lost Souls like normal, Lucida is the one to return Gaster to normal.
