Extract from Fantastic Beasts and Where to Find Them

By J.K. Rowling

The Streeler is a giant snail that changes colour on an hourly basis and deposits behind it a trail so venomous that it shrivels and burns all vegetation over which it passes. The Streeler is native to several African countries, though it has been successfully raised by wizards in Europe, Asia and the Americas.
