Bagged Then Tagged! - S12.E43

Ash and Dawn have a tag battle against Lyra and Khoury. Ash sends out Monferno and Dawn sends out Cyndaquil. Lyra sends out Chikorita and Khoury sends out Totodile. During the battle, Totodile evolves into Croconaw. Ash's Monferno finishes up with Mach Punch and defeats Croconaw and Monferno teams up with Cyndaquil using Flamethrower and Flame Wheel. Ash and Dawn eventually win the battle, and Lyra and Khoury leave the group and go back to Johto, but not before Khoury's father gives Brock the Pokégear as a thanking present to them by showing Lyra and Khoury a little bit of Sinnoh.
