Let's Go Everyone! Let's Catch It! (Japanese: みんなでいこうぜ！つかまえようぜ！) is the second Pokémon Tretta Fes series set, and the seventh overall. It features 48 Tretta.
Let's Go Everyone! Let's Catch It! features the Pokémon Tretta debut of the Alpha Pokémon Arceus as this set's Legend-class Tretta. The standard Tretta are colored a dark shade of green called "jungle green". All Search Mode locations remain the same as the previous set for the first time, and all, apart from Beach, have an autumn theme.
For players with Tretta Reports, Let's Go Everyone! Let's Catch It! replaces the previous roster of Turtwig, Chimchar, and Piplup as starting Partner Pokémon with Bagon and Beldum. Pokémon Comp is also expanded: capturing the same Pokémon five times during gamepaly activates Friend Power (Japanese: なかまパワー), which increases the stats of Super-class, Hyper-class, and Master-class Tretta featuring that Pokémon in Battle Mode.
The Catch Bonus aspect of the Weekly Bonus feature was also amended in this set: the bonus Poké Ball added to the roulette was changed from an Ultra Ball to a Master Ball.
