Even after Sketchbook poured black paint over the Yellow Guy's clown painting, someone still appreciated the work the Yellow Guy put into the ruined picture enough to frame and hang it up in the puppet's living room.
Also it could mean that the puppets don't hold any resentment against Sketchbook. As they were seen in various situations lying about the house
What are the puppet's favorite colors? The Red Guy likes blue, the Duck Guy favors red, and the Yellow Guy prefers green. In other words, their favorite colors are each other's hair (or feather) colors.
The fanon idea that Roy was the in-universe source of the 96,000 pounds out of concern for his son.
At the end of the third installment, the last name in the credits thank "all the kickstarter backers & Roy."
The fact that some of the DHMIS Kickstarter reward options include a drawing from Yellow Guy. It's nice to see that he's still being creative after Sketchbook's repeated insults.
Fandom example: On July 16th, 2014, someone entered a DHMIS Flock Draw room and started messing up the drawings. A few hours later, the person and the fans got to talking, and it turned out that the apparent troll had never even heard of DHMIS and just wanted to have fun with the Flock Draw. Long story short, by the end of the day, the fans and the person were drawing together, and the person was made an honourary DHMIS character.
As bad as the Creativity Explosion is, one of the quick shots is of all three of the puppets hugging each other and dancing in a circle. Aww...
The ending of DHMIS 3, where the Red Guy and Duck Guy find Yellow Guy and apologize to him, giving him an egg, and saying they love him.
Not to mention the meta fact that this time, NOTHING HORRIBLE HAPPENED TO ANY OF THE PUPPETS! All the bad stuff was a DREAM!
Unless the caterpillar+Yellow Guy hybrid at the end implies that Shignold raped him...
As one DHMIS blog points out, DHMIS 3 is the first time Red Guy seems genuinely happy about something, which is really sweet.
'Maybe I could hold your hand, and together we can understand...' That line is really, really sweet.
'Your heart beats hard like a big love drum, calling for your special one. So be patient! 'Cause just maybe your special one will come!' is also quite cute.
"Hehe! I love you too, furry boy!" Yellow Guy is so unabashedly happy in the woodland creatures' presence, although this makes what happens next all the more horrifying.
In "Time" Sketchbook is seen casually sitting in the Red Guy's room. When you think about it, it's sort of sweet and may imply that the puppets do actually care for the Sketchbook as their friend, even after its manipulative lesson in the first video.
When Yellow Guy comments that he'd like to be as smart as a computer, he has a brief Imagine Spot of himself with a gigantic brain and an adorably goofy smile on his face.
Becky uploaded a video to Instagram of Red Guy repeatedly opening a garbage bin with a log in it while chanting, "The log is in the bin." Surprisingly, it's quite heartwarming, given that Joenote who voices Red Guy is obviously trying to hold back laughter. It's like Red Guy has found something that's genuinely entertaining to him.
In Episode 5, Yellow Guy stops listening to the teachers because he misses his friends, which is a big step from Episode 3, where he ran out on them and almost joined a cult.
It's also implied at the end that Red Guy is still alive and trying to help Yellow Guy and Bird Guy from outside their reality.
As depressing as it is, the beginning of Episode 6 shows just how far Yellow Guy has come, and how much he cares for his friends.
If you look closely during the beginning, you can see a couple pictures of the three puppets together, and they actually look happy. One is of the three standing around a birthday cake (in Yellow Guy's album), and another is of them at the beach (on the nightstand). In both pictures, Yellow Guy and Duck Guy are smiling.
Red Guy singing the song from the first episode can be seen as this.
More than just that. Red Guy ends up in a dull, bland version of reality entirely populated by copies of himself, and it seems he realizes that, even though his reality is safe from murderous and psychotic Teachers, it is dreadfully boring, while he and his friends got to live in a colorful, vibrant environment made out of felt. And therefore, to supplant the random pounding of the bar's "pianist", he starts to sing the creativity song, and embrace everything he has derided.
Episode 6 ends on an oddly hopeful note, even despite the Here We Go Again implication: The puppets are all together again — so Red Guy and Yellow Guy don't have to be lonely anymore, and Duck Guy is back with them. The date has finally changed, suggesting that maybe things won't end up the same way this time around... and, most cheering, everyone has become their favorite color!
Putting aside the creepy fuel of Roy using a long arm to get Red Guy's attention, you end up seeing that he's pointing at the screen, where Yellow Guy's crying for help. As if telling Red Guy to save his son.
Alternately, the scene can be read as Roy trying to stop Red Guy from interfering with Yellow Guy's torture, which, while not beingheartwarming in itself, makes Red Guy's subsequent unplugging of the machine a heartwarming (and awesome) move.
