The canon was pretty much a Sumatra Zinger but could shoot ten times in total, created using the bodies of ten Empyrean Zinger Scouts.
As Inala activated it, a strong wind was generated as the canon began to suck in air. As ten pairs of lungs were sucking in air, the generated force of suction was very strong, enough to cause a drop in pressure within the basement.
Thankfully, Inala kept the windows of the house open, hence there was enough influx of air. While the canon was charging up, the group of Empyrean Zingers brought a second canon, followed by a third, a fourth, and so on.
While he was digging, Inala created a bunch of Life Bombs and gave them to the Empyrean Zingers that he had created previously. Their task was to hatch these Life Bombs.
