S1, E5: One morning, Hector and Marsu wake up to a disagreable surprise: they--and a big part of Palombia--are beneath an enormous bell jar. It's another one of Blueprint's schemes to imprison Marsu so he can raze the forest in peace. Stuck under the glass bell jar, our heroes suffer from the increased greenhouse effect... With no wind, the Leekysoupi doesn't move, it's blocked off by the glass jar; Aunt Diane's plants dehydrate... The only solution comes from the Leekysoupi. The river starts to produce an algae which eats glass and turns it into sand. Hector and Marsu construct a hot air balloon and they take the algae up to the summit of the bell jar... The algae attacks the glass and in no time, our heroes are free in time to deliver a lesson to Stroy and Blueprint.
