Helium in a Jar

 is the first level of Even More Bloons.

Completion
This level can be done in just two shots: the first must pop the Helium Bloons' glasses, then the second shot must pop the Helium Bloons themselves. However, note that they will float at the time their jars break so be accurate enough when popping these bloons.

Trivia

 * It is the first level in the Bloons series to feature Helium Bloons.
