The ket boglin will seek out ‘nests’ inhabited by other ket boglins and will stay for up to 2 weeks before venturing out for more ket. During the summer months these nests can grow to extraordinary sizes and form in fields and woods. Walkers are advised to stay clear however the ket boglins are mainly harmless and rarely bite. If you are approached by a ket boglin, try to stay calm and attempt to direct it back to its nest. Do not offer food as ket boglins rarely eat and may cause further confusion, although they have been documented eating pot noodle on occasions. 2002 - Ainsworth.
When you find various fine, or tattered, under-bridge denims (or possibly from the sewers), boiling denim is the process of sanitizing them. This works best in a water-filled denim pot on a hotplate. Obviously, you finish them on the radiator.
Charlie was boiling denim again. When is he going to stop foraging under bridges for eggs and denims?
