Monday Mystery

Last week's photo:



saw most recognise it as



some sort of plug in aroma therapy type of gadget. In fact this one is formulated to help calm dogs in stressful situations. I used it for Penny as she was badly stressed by loud noises, especially fireworks and thunder. Though not a complete cure it certainly helped. As for the faint scent given off - to my nose it reminded me of the odour of freshly dug damp earth. These are not an instant 'cure'. I found it worked best when plugged in for a few days before any known or suspected noisy events and not used unless needed.
Many thanks to Adrian, Wilma, Ellen D., Ragged Robin and Kev Scott who were all near enough to the answer.

I suspect that this week's 'bump picture', as FX Studio Pro calls the process,



will be a tad easier to identify. If you would like to make a guess please leave it in the comments. They will be revealed, with the answer, next Monday.
