Derp Dump: Golden Harvest and Derpy switch places as the grey Pegasus is jettisoned from the kart and sent flying at opponents taking control of them and sending them swerving off course.
Food Fright: Golden now takes the role of attacker and begins digging in a bag of old rotten veggies and throwing them at anypony nearby.
Perish Song: Octavia begins playing a somber tune with her cello and can give a tear jerking performance that is so effective it causes the engines of nearby karts to conk out.
Bass Quake: Vinyl gets to play with her favorite speakers and lets loose with a thumping bass that shakes the ears of ponies and the course. The sounds eventually shake the opposing teams off the track.
Bon Bomb: Bon Bon picks out a sweet looking treat then hands it off to another driver. They may try to eat it but will end up having a blast instead as the explosion launches them into the air.
Lyrical Lullaby: Lyra takes out her lyre and begins playing, soothing any other drivers within earshot and making them go to sleep. This is one tune opponents will want earplugs for.
Pecking Order: Gilda takes to the skies and begins pestering other drivers, pecking and clawing at them, allowing Rainbow to speed past them and possibly into the lead.
Rain Boom: Rainbow Dash brings in her favorite cloud then picks out an unfortunate driver and begins hitting them with lightning. The shock will arrest the opponent movement for a few precious seconds and probably their hearts.
Barn Afterburner: Thanks to her sister, Applebloom, AJ has a fancy new invention to hitch onto her ride. With the push of a button the rocket sends the pair racing across the track at speeds even Rainbow Dash would envy.
Fashion Crash: Rarity is a well known seamstress and can put together a beautiful piece in no time. This day though she’s feeling generous and wants some pony to have it free of charge. Try not to run off the track though when the new dress hits you in the face.
Cheap Trick: The Great and Powerful Trixie has something special to show you. Trixie summons her hat and cape for a great act and picking out a pursuing team will drape her cape over them and with a wave of her wand will make them vanish. Only to reappear in last place.
Teleportation Trap: Twilight puts her extensive powers to use and will take hold of a team in her telekinetic grip and in a bright purple flash send them further back in the pack. It may take a few seconds for the other drivers to figure out where they are.
Animal Crossing: Fluttershy signals for her wild friends to run across the track at a certain point blocking other drivers from continuing forward while they hear "I’m sorry" from the apologetic Pegasus.
Pie Toss: Pinkie brings an oven from out of the blue (don’t ask how she got it.) and bakes up treats that would make anypony’s mouth water. But these sweets aren’t for eating… they’re ammunition. The party mare will begin hurling the baked good (and bads) all over the track splattering anypony unfortunate enough to be within range of the sugar fall. Even after the ammo has been wasted it stays on the track and will send any kart that hits them spinning out of control.
How do you like that? Go ahead, tell me. (I also wrote this on your Derpibooru entry.)
I know i have been pointing out a few flaws lately, but that doesn't mean I'm hatein. I think your pictures are really really good, Pinkie Promise... but...I think Shining Armour should have been riding with Twilight.
Hah! Brilliant! Ideas: - Cadence & Shining Armour - Doctor Whooves, instead of Carrot Top - Celestia & Luna - Big Mac & Cheerilee - The CMC (They're small, they can fit (Or you could could include Babs Seed and put her with Applebloom) - Diamond Tiara & Silver Spoon
