I have decided to start a new trend by writing episode synopsis that gives a full detailed description about said episodes. This episode i'm about to write one out for is Indigo League episode Bad to the Bone. Anyways, without further ado, we can go ahead and get this started.
As the episode starts off, we see Ash, Brock, and Misty back at Pallet Town, ready to head out. Before Ash leaves, he asks Professor Oak to give him some advice about competing in the Pokemon League. Professor Oak gets upset with Ash's lack of preparation and tells him if he can't be prepared, he may as well give up his dream of competing in the Pokemon League. Oak then changes his tone of voice and says if Ash wishes to compete, that he best hurry out the door now. We cut to the next scene where Ash's mom is packing the last of Ash's things into his bag (snacks if he gets hungry, a change of clothes, etc.). After heading out, Ash, Brock, and Misty are walking through some tall grass when all of a sudden a dark shape moves by in a blur. The dark shape reveals himself to be Otoshi, who challenges Ash to a battle. Ash is hesitant at first, but soon decides to battle him anyways. The battle starts out and Ash uses Bulbasaur to battle Otoshi's Marowak. Despite the type advantage, Bulbasaur loses to Marowak. After Bulbasaur is unable to defeat Marowak, Pikachu is called in instead, which is able to dodge all of Marowak's attacks and defeats it with a Thundershock. After the battle, we learn Otoshi lost his badges when him and Marowak ran over to a basket of fruit in the road, which was a pitfall trap dug by James and Meowth (the badge thieves). Taking the next course of action, Ash, Misty, Brock, and Otoshi decide to interrogate James and Meowth themselves to ask them where the badges are. Meowth explains Jessie took them. After the quick inspection, James and Meowth take to the sky again in the Meowth balloon and spot Jessie about to take badges from another trainer further down the path. As she is about to snatch all his badges away, a bomb is tossed in her direction, throwing smoke everywhere. After doing the motto, Jessie gets upset at her opportunity to take the trainer's badges being stopped by James and Meowth. Otoshi, along with Ash, Misty, and Brock suddenly show up to get the badges back. Jessie challenges Otoshi to a battle, of which she uses Arbok and Otoshi uses Doduo. We cut to the next scene with Marowak walking through a forest and suddenly seeing a couple other trainers and their Pokemon, of which include a Hitmonlee, a Flareon, a Nidoran (m), and a Chansey. Marowak starts having flashbacks of him and Otoshi. Flashback scenes include Marowak and Otoshi under a waterfall, Marowak and Otoshi jumping through a flaming hoop, and Marowak and Otoshi enjoying watermelon together. These past memories become too painful for Marowak to bear and it heads back to return to its trainer. Meanwhile, back with Doduo and Arbok, things seem to be going not so well, as Arbok proves to be too strong for Doduo to handle. Eventually, both of Doduo's heads became distracted and start fighting each other. Arbok takes advantage of Doduo's distraction and finishes the battle by wrapping its coils around Doduo's body. Just as Jessie is about to toss one of her Pokeballs at Doduo, a spinning bone club knocks it out of the way, which is revealed to be Marowak's bone. With Marowak back, Otoshi is finally able to resume the battle in which Marowak starts out with Focus Energy and then beats Arbok with Bone Club and finally defeats it with Bonemerang. We learn that this second half of the battle marks the debut of Arbok's newest move Double-Edge. In order to stop Arbok from crashing into Jessie, James sends in Weezing, which Ash uses Pikachu to stop. After Otoshi gets his badges back, the episode ends with Brock, Misty, and Ash heading towards the Indigo Plateau.
