Top 10 things I never thought I'd name a drawing.

More Wings of Fire of course, and just when I was thinking the series wouldn't have any gay male dragons (but 3 lesbian couples!), it finally delivered in the last book.
They don't have many lines, but like the Sundew and Willow drawing, here are a few from book 15 (spoiler warning):

'"The pink RainWing shook his head and snuggled farther into the hammock. "Nuh-uh. I need more Pineappletime."
Pineapple laughed. "Your entire life is Pineappletime. I'm always here for you."
"Because I'm very cute," said the pink dragon with his eyes still closed.
"And excellent at tree gliding. And related to royalty."
"Hmm," said Pineapple. "If those are my reasons, I must be a pretty shallow dragon."
"No, no," said the pink dragon. "You are SO deep. The most deep. Very deep. So, so, deeeepy..." He trailed off, making snoozy snoring noises.
Pineapple chuckled softly.
"All right. I'll prove what a deep boyfriend I am by letting you drool on me, just this once."
"Very cute drool," the pink dragon mumbled.'

'Pineapple bumped him with his snout. "You've done lots of helpful things," he said. "You helped our amazing queen become queen. Let me take a turn."
"All right, yes, love you, bye!" Jambu said, wriggling all the way back into the hammock.
Pineapple laughed as he extricated himself. Once he was hovering in the air beside the hammock, he reached in and squeezed one of Jambu's talons. "I'll miss you, too."
"Deep and noble," Jambu mumbled sleepily.'
