We report here our finding of two new blueberry galaxies using optical IFUspectroscopic data from the MaNGA survey. Both the blueberries are found to becompact ($\leq$ $1 - 2$ kpc) starburst systems located at the outskirts of LowSurface Brightness (LSB) galaxies. Our blueberries have the lowest stellarmasses $\sim$ 10$^{5}$ M$_{\odot}$ amongst the locally known blueberrygalaxies. We find a significantly large mean metallicity difference ($\sim$ 0.5dex) between the blueberry sources and their associated LSBs. Moreover, theradial metallicity gradients in our blueberries are also different than theirrespective LSBs - suggesting that these had significantly different metallicityhistories. The likelihood of survival of these blueberries as TDGs is analyzedbased on their structural and kinematic properties. Our analysis shows thatalthough the two blueberries are stable against internal motions, they wouldnot have survived against the tidal force of the host galaxy. Based on thevelocity difference between the host LSBs and the blueberries, it appears thatthey are compact, starburst systems in their advanced stage of merger withthese LSBs situated in a dense environment. Implications of our findings arediscussed.
