Shiranui saw the bizarre spectacle and before he could comment on it, what looked like a ton of bricks with eyes encased him in a mini tower.  "Nayamashii, Toxic!"  He sent his Salazzle out and the latter sprayed a caustic toxin that badly poisoned the brick colony and sent it flying apart until it reassembled in front of Shiranui as a four-legged square tower with a window.  The tower launched two bricks at Nayamashii for a two-hit Rock Blast and the Salazzle was knocked out from the blows.  "Nayamashii, return; Tsuchi, use High Horsepower!"  Shiranui switched the downed Salazzle and sent his Mudsdale out.  Tsuchi reared onto his hind legs before charging at the tower.  The Mudsdale slammed into the tower with his one-ton mass and Shiranui threw a Beast Ball at the brick colony.  The ball shook once and pinged shut to Shiranui's surprise, indicating a critical capture.  Naming his new catch Atsumeru, Shiranui scanned both it and the juggling clown.
"[i]Stakataka, the Rampart Pokémon (alias: UB Assembly).  It appeared from an Ultra Wormhole.  Each one appears to be made up of many life-forms stacked one on top of each other.[/i]"
"[i]Blacephalon, the Fireworks Pokémon (alias: UB Burst).  It slithers toward people.  Then, without warning, it triggers the explosion of its own head and takes advantage of opponents’ surprise to rob them of their vitality.  It’s apparently one kind of Ultra Beast.[/i]"
