Mega Alolan Exeggutor

Mega concept for a most exeggent Pokemon.

Design: The lil' head grew huge! Also wing-like leaves, funky leaf colors, hair, eyebrows and beards.

Type: Grass/Dragon.

Ability Ideas:
Rock Head is fitting and would work great with Wood Hammer... and nothing else.
A Cloud Nine-like ability could allow this tall dude to tower over weather effects.
A Touch Claws variant called 'Tough Head' could boost non-physical Phychic moves in addition to contact moves.

Current Stats for Reference: 95/105/85/125/75/45 (Total 530)
Stats 1: 95/135/95/135/75/95 - Stats 2: 95/125/125/125/125/35

Both ideas highlight Exeggutor's mixed potential. The first keeps his Special Defense low and gives him a huge speed boost, which doesn't fit the huge head but in addition to making him feel more ludicrous, fits his draconic self and wing-like leaves. Also has three stats at 95, his HP. In the second scenario he does get much slower, in order for all other stats to match one another.
