^ Life Orb as the item, throw on Swords Dance over Toxic. Toxicroak's too frail to abuse Toxic properly, and Swords Dance is quite a useful boost for him. Dry Skin helps him heal off Life Orb damage by switching into Water-type attacks.
Exeggutor needs some love. Especially considering that his current set is worthless due to Calm Mind not being a move he can actually learn.

WHY DOES THIS THING NOT GET EARTHQUAKE. Oh, and moveslots depend on personal preference. The last slot could be a lot of things, Stun Spore and Return being other potential moves.

All-out offensive. STAB Leaf Storm basically wrecks everything without a resist and lots of special defense. 220 Spe gets something... idk and idc what though. It's supposed to be 216 usually, but HP Fire lowers the Speed IV by one.

Not exactly the most brilliant scarfer ever, but it works. If you aren't running Explosion, Timid is the better choice, with the 12 EVs in SpD or Defense. 244 Spe gets Max Speed Base 105's. You could run Max if you're aiming for Liepard, but meh.
