Oh there's a dex entry as well
Sun: Its destructive power has increased dramatically.
When readying an attack, the heat from its beak can cause
anything flammable within a 3 meter radius to spontaneously combust.
Moon: Mega Evolution has caused it to significantly grow in size.
Its chest cavity is filled with flammable gas that super-heats the seeds it
stores in its beak, which it then launches at a speed of over 400 m/s.
3.1m (~10'02")
104kg / 229.3lb
and some extra info
"It's been a while since I've drawn any original fanmade Pokemon art,
so here's a design for a Toucannon Mega Evolution.
The design is somewhat based off of both the channel-billed toucan and hornbills.
Unlike regular Toucannon, its beak looks fairly plain. When it heats it up for an attack,
however, its cheeks glow, the yellow parts of its beak and horn fade to a fiery orange,
and the black parts of its beak and horn turn red-hot in color.
Fun fact: I actually got the idea for this from a dream about a new Pokemon game.
The Mega Toucannon in the dream looked a little different and came in a large variety of
different colors, but I basically just simplified down what I remember of its design into
something that I figure would actually fit in a real Pokemon game. Also in the
dream, it was shown to be a little over twice the height of a
normal Toucannon (there was even a trainer silhouette for size comparison).
If this were legit though, it probably only be a foot or so taller."
