Pokémon Colosseum/Heartwarming

Pokemon Colosseum

 * When Wes and Rui break into Plusle's cell, the little guy looked really happy to see you. Personally I thought that was heartwarming.
 * Seeing Celebi appear after using a Time Flute.
 * Receiving Jirachi from the Pokemon Colosseum Bonus Disc. What a Tinker Bell imitator! I got to admit though, the way it blinks at you is just so cute!
 * Wes has an Espeon and Umbreon, two Pokemon who can only be obtained via friendship. Even when he was a villain he was nice to his Pokemon! Awww!
 * Not gonna lie, any time a Shadow Pokemon gets rehabilitated and reopens the door to their heart gives me the warm fuzzies. That triumphant fanfare really adds to the moment.

Pokemon XD

 * The backstories behind Eevee and Togepi. Awww!
