Flask

 is a Tier 5 Tank that upgrades from Twister at level 60.

Design
The has a base identical to the Twister's but it loses its decorative trapezoid at the tip. For a while, this was its whole design until later versions where it gained a thin decorative red barrel similar to those of the branch.

The tank's missiles are also modified, possessing much wider barrels colored the same blue as you appear to yourself in Free For All. They have a smaller decorative barrel layered over them colored the same red as Laser's deco or the tank's own deco in later versions.

Technical
The fires twisting bullets with two barrels per bullet just like its predecessor; but its bullets fire rapid streams of lasers instead of bullets.
