no bubbles or mucus just on the inside side of the mouth. no bubbles what so ever. Only had the 2 new dinkers since thursday...have yet to feed them or do anything other than QT them and switch things around today due this issue....as far as normal in regards to this particular snake...i have no clue what normal would be....she behaved as "normally" as my 3 established BPs do when I have them out in the house with me.
