(I knoooow, handwriting should NOT be used in future sketches)
After making up  SkruffyHusky's padded Meganium form here, he wanted to see it get bloated from some "overhealing" via Synthesis. Now, since I was getting into Lurantis in Pokemon Sun, and learned that it can use Sunny Day (which intense sunlight boosts Synthesis), that's how this idea spawned.
The whole Sweet Scent hypnosis-esque thing is kind of based on a conversation while I was making the Meganium sketch from earlier. That sneak, using Sweet Scent and having my Lurantis use Sunny Day and Synthesis with him. >_>
