Bellsprout is Kyle's un-nicknamed Bellsprout in his Let's Play of Pokémon Crystal. It used to belong to Emile
Emile sought a Bellsprout to demonstrate the in-game trade with Kyle in Violet City, particularly for players who picked Chikorita as their starter. After a lot of searching he found a female Bellsprout at Level 5 that knew only Vine Whip, and sent out Darmani, who was weakened from the various battles up until then. Bellsprout endured a Tackle with ease before finishing it with Vine Whip. Next, Emile sent out Odairu, who weakened it significantly with a Scratch attack before Emile threw a Poké Ball. Bellsprout broke free after three shakes and nearly knocked Odairu out with another Vine Whip, but Odairu healed himself with a Berry. Emile threw another ball, and this one succeeded in catching the Bellsprout.
Emile then traded Bellsprout for Kyle's Onix, Rocky.
