Inala wasn't wasting his time while getting close to Wittral. No, he was also spying for information about the rest of the Cooter Clansmen on the island.
As he observed them, through his attention to detail as an artist, he noted how they moved and behaved while talking to each other, their body language and facial expressions regarding various topics, etc.
Scattered across Fral Island were his Empyrean Zinger Scouts hiding within stones, listening to their every conversation. All these data were transmitted to him by a series of shrieks at opportune moments.
Inala then relayed this information to the Empyrean Zinger Scouts who began to build puppets for every single Cooter Clansman.
When he enveloped two of them in a Prana Bomb, shrunk it, and swallowed it, the Prana Bomb returned to its original size once it was in his biome. It shattered to reveal two unconscious Cooter Clansmen.
