Sonic Bomm

The Sonic Boom upgrade.

Sonic Boom is an upgrade for the Boomerang Thrower that appears in Bloons TD 2, Bloons TD 3, Bloons TD 4 and Bloons TD 5. This upgrade allows the Boomerang Thrower to pop frozen bloons. Just for that reason, Bloons TD 2 states that Ice Towers work the best with Bomb Towers or Sonic Boom Boomerang Throwers nearby. The upgrade picture is of three yellow boomerangs gradually increasing in size. In Bloons TD 5, this is the first upgrade on the second path. It costs $85 on Easy, $100 on Medium, $110 on Hard and $120 on Impoppable.


  • In Bloons TD 5, when the tower throws the boomerang with this upgrade, a sonic wave can be seen briefly.
    • With Double Ranga, only one sonic wave is shown, even though there are two boomerangs being thrown.
  • In Bloons TD2, the description for the Boomerang Thrower says Sonic Booom instead of Sonic Boom.
  • The BTD5 Artwork shows a Boomerang Thrower with Multi Target unlike BMC, it has the correct mark on the tip of the head.
  • The BTD5 Artwork shows that he is happy and opening his mouth but in contrast in BMC, he does a surprised face.
