S03E09 — Why!? Rima-senpai!

Rikka drags Amu to the flower beds, showing her the new buds that have grown. Rima follows them and says that they need to thin out the flowers, because the buds can't absorb sunlight properly if they're too close together. Rikka disagrees, saying all buds should have a chance to become flowers. Amu tries to reason with Rikka, but she misunderstands and runs off. Later on, she finds an X Egg. She starts to say that the egg isn't needed. The X Egg quickly retreats, Rikka running after it. Amu and Rima discover the X Egg and transform into Amulet Heart and Clown Drop. Rikka explains to them that the egg wants to be a baseball player, but is no good at catching the ball. Amu tells the egg that it won't happen if it doesn't try. Amu purifies the egg.
