Focus Lotus blossom
From Jenny Everywhere Wiki
The Focus Lotus blossom was a flower cultivated by Jenny Everywhere in one universe on “a remote antipodean island”.
Residue from this blossom could be distilled into a chemical which “shifted one's brain properties from a state of funfair-induced erratic grasping-for-immediate-sensory-pleasures to an uncharacteristic stateof constant and sustained focus”, ideal for experiencing a particularly great circus performance.
