Mandi's Exeggutor is the Pokémon Mandi decided to use first against Ash in the first round of the Kanto Pokémon League.
Exeggutor was up against Ash's Krabby and started off well as its Psybeam to force Krabby to jump into the water. Then, using its Psychic ability, Exeggutor created a whirlpool in the water, trapping Krabby inside. As Krabby struggled to get out of the whirlpool Exeggutor started to bombard the pool using its egg-bomb attack that made Ash attempt to switch Krabby out, although unsuccessful due to the whirlpool trapping Krabby inside.
A smug Mandi was caught off-guard when Krabby managed to compose itself, launch out of the water and used Vicegrip on Exeggutor's leaf, clamping on hard as Exeggutor tried to shake it off. A quick leer attack, followed by a Stomp KO'ed Exeggutor and Krabby had won its first ever battle.
Mandi looked on as he watched Krabby evolve into Kingler but quickly regained his flair as he release his second Pokémon, a Seadra.
