Mammoth Clansmen were basically spoiled brats in terms of food, having never faced the issue of hunger. The Empyrean Tusk always produced more than enough food for their needs.
Inala wasn't worried about that even in the likelihood of him leaving the Clan. After all, as long as he slaps a Pranic Beast with a Prana Bomb, he could have his fill in terms of both nutrients and Prana. The fluid within the Prana Bomb was that nutritious once it absorbed Prana to the limit.
Zingers typically only consume the Prana Bombs. All they consumed other than that was water from the Baobab Trees.
Hence, Inala had been a tad careless in his preparation regarding food. And that came to bite his ass now. There were no Pranic Beasts in the vicinity. 'Do I have to use my Prana Hand on the people? No!'
