Pokemon Best Wishes! EP18 - Sewaddle and Burgh in Pinwheel Forest

Ash, Iris, and Cilan enter the Pinwheel Forest, where Pikachu is attacked by a wild Sewaddle, the Sewing Pokémon. Ash decides to capture it, but it surrounds him with a String Shot attack and escapes. Deeper in the forest, the group comes across a large tree where they believe the Sewaddle is hiding. They climb up it and find a giant cocoon, only for it to be revealed to be Burgh, Castelia City's Gym Leader, who is in the forest to sketch some of the wildlife. As he shows the group his drawings, the Sewaddle attacks Ash again, only to nuzzle up to Burgh. It seems that Sewaddle likes everyone in the group except Ash. However, after Ash saves Sewaddle from a group of Woobat, Sewaddle begins to warm up to him. The next day, Sewaddle is abducted by a Patrat, which reveals to the group that another Patrat has fallen ill, before Sewaddle attaches itself to a Deerling and falls in a ravine towards a waterfall. Ash dives in after it to save it, and is then saved by Burgh's Leavanny, Sewaddle's final form. Happy for being saved, Sewaddle allows Ash to capture it (with Ash transferring one of his Pokémon back to Professor Juniper so Sewaddle can stay with him), and later the group parts ways with Burgh, who tells Ash he will be waiting for him in Castelia City.
