That's No Party Cannon!
The crash had knocked Samus unconscious for a good few hours, her damaged gunship unable to land on the strangely pastel coloured planet.
Coming around, she ran a systems check on her suit. Systems green. For once she hadn't lost all of her weapons systems in the crash. Reasons for concern; weight on her chest, possibly a native life form from the heat it was giving off. Samus opened her eyes. Pinkie Pie stared into them. "Hi!"
Samus immediately pulled off the strange creature and rolled to her feet, levelling her arm cannon at the bouncing pony. She had seen more innocent looking creatures rip apart entire squads, and she wasn't taking chances.
Pinkie bounced.
"Ooh, ooh! Who are you? Can you talk? Should I get Fluttershy? Ooh, ooh!" she giggled delightedly. Samus narrowed her eyes behind her visor, and fired a warning shot above Pinkie's head. Behind them, a tree branch exploded. This only seemed to excite the pink horse more.
"Silly billy, that's not how you load a party cannon! Let your auntie Pinkie show you how." and then Samus realised that the horse was now behind her and fiddling with her arm cannon. Swinging around, she established the being as a threat, and prepared a charge beam.
Pinkie bounced and giggled, and then Samus fired a set of streamers at her, followed by two cakes and a set of party hats.
Samus swore.
A/N: I dunno.
