After what seems to be a very dangerous situation from Professor Birch getting chased by this pooch on Route 101, You decided to help him out and select a Pokémon of your choice. (Any Starter can work here, which is Treecko, Torchic, or Mudkip.)
Oh my freaking god. No...NO! You...YOU ACTUALLY encountered a shiny Poochyena?! N-NO WAY!!
You must be the luckiest person in the world! Holy moly! You were running around in joy, now excited about your new findings! You...you gotta catch it! YOU HAVE to catch it!
...Alright, time to rummage around in your bag and...
...Oh.
Oh...no.
To your horror, you realize that you haven't even been equipped with Pokéballs! AUGH...NO! You have NO Pokéballs. NONE, NADA, ZILCH, NOTHING!!!
However, that darn Poochyena is too busy just growling and barking at you like it's tough as nails.
What to do...
Since your starter is out, you can attack the Poochyena...or...probably delay the inevitable. Because with no Pokéballs, you can't catch it.
...Aw, what a world...
