Pebbler

 is a Tier 4 Tank that upgrades from Punt Gun at level 45.

Design
has the same base as Punt Gun but with 4 barrels on each side. Each set of barrels is made thinner, which now leaves some empty space on the outside of the base. The sets of barrels also gain more barrels in each stack, making it appear longer.

Technical
The fires many more bullets than the Punt Gun with greater bullet speed, but they are weaker and smaller.
