Yoko is given the day off from work with Hiromu and Ryuji assigned to accompany her on a surprise tour for their Buddyloids. Starting with having Gorisaki see the animals at the Kamine Zoo, and then a visit to the Tokyo Dome Attraction theme park for Usada to enjoy the rides. However, a Metaloid signal is detected nearby and forces the Go-Busters to intercept it, much to Usada's dismay. Finding Tubaloid, the Buddyloids help get the civilians to safety while the Go-Busters deal with the Buglers before they are alerted to a Vaglass Megazord coming in 2 minutes and 30 seconds, along with discovering that Kuroki is not in the base. As Red Buster heads off in the CB-01 to intercept the Tubazord, Blue Buster and a fired up Yellow Buster battle Tubaloid. However, though realizing both Tubaloid and the Tubazord are using weak attacks, the former being easily hurt by Blue Buster and the later being easily destroyed by Go-Buster Ace, Tubaloid escapes. While the others track down Tubaloid, after having Usada go on the rides, Yoko meets up with Hiromu before revealing to him the surprise she has in store for Nick and hints about a back-up for him and Ryuji. By then, Tubaloid makes his move again with Hiromu taking the hit meant for Yoko. After being alerted to another Metaloid being created with another Vaglass Megazord to appear in 28 minutes, the Go-Busters fight Tubaloid and the Buglers while Gorisaki takes Usada back to the base. Seeing Yellow Buster dodging Tubaloid's fanfare sound wave, Red Buster and Blue Buster realize that the Metaloid has been made to counter her abilities and destroy him before he completes his objective. However, Tubaloid 2 appears, walking through what remains of his predecessor to subject the Go-Busters to his much more powerful musical attacks.
