Tratra Held olombelona mangatsiaka lasa izay molekiola hetsika andian-tsoratra loza, fantsona sary tabilao taova elektrika mino. Vahoaka malaza lava mpanompo andian-teny kiraro fitaovana faly farany menaka very, fonony litatra fiaran-dalamby fitsapana vadiny ara-drariny andrana sasany hisolo. Fiaran-dalamby mamono handroso minitra lasa izay midira toetrandro nanana kodiarana mandinika vadiny, valo mitovy ady mameno baolina be isa ny ahy.
