Pokémon : S5 | E20 – An EGG-sighting Adventure!

While Ash wonders what will hatch from his Egg, Team Rocket is also keen to find out. Meowth thinks it might be a Legendary Pokémon, though his teammates have their doubts. Jessie declares that they will steal the Egg, and her teammates cheer to the idea. Later, storm clouds begin to gather, causing Pikachu to get excited from the electricity. Brock says that there is a Pokémon Center nearby and they should get there as soon as possible. A bolt of lightning strikes nearby and ruins Team Rocket’s next plan. The group rushes into a Pokémon Center. Brock eyes off the resident Nurse Joy, but Misty pulls him away by the ear. Joy gives the group a room, admitting they are her only guests for the night.

Meanwhile, Team Rocket waits for the lights to finally dim before breaking into the Center. They tiptoe through the hallway Wobbuffet emerges from his Poké Ball and almost disturbs the peace with his loud shout, but Jessie and the others beat him to the ground. The trio soon reaches the group's room. Meowth picks the lock with his sharp claw. They wonder how they can easily get the Egg, so they tie Meowth onto a fishing pole. They sneak their way in, and then they fuss over who gets credit for the Egg. Though their squabble wakes up Togepi, who Teleports the Egg outside using its Metronome. The trio is startled when Brock starts talking, except it's only in his sleep. The Rockets turn their attention to the Egg again, but it seems to have vanished. They are distracted again, this time by Wobbuffet who appears with an apple in hand. Jessie decides a snack break is in order. Wobbuffet points them to a basket of fruit in the kitchen down the hall. Rushing to the kitchen, Team Rocket trips over Wobbuffet and they all fall flat on their faces. They shush each other to avoid raising any alarms. Later outside, an infant Kangaskhan approaches the odd Egg case with caution. She taps on the glass out of curiosity, causing the Egg to simply roll out of its case. Her mother comes along. She promptly puts the Egg and her baby into her protective pouch before wandering back into the wilderness.
