Mbh 13.85.4b

Let that eater of sacrificial libations, who is a mass of energy, be searched out. That illustrious deity will accomplish this desire of your hearts." Hearing these words of the Grandsire, the high-souled gods then proceeded to search out the god of fire with hearts cheerful in consequence of their purpose having been achieved. The gods and the Rishis then searched every part of the three worlds, their hearts filled with the thought of Agni and eagerly desiring to obtain a sight of him. Endued with penances, possessed of prosperity, celebrated over all the worlds, those high-souled ones, all crowned with ascetic success, sojourned over every part of the universe, O foremost one of Bhrigu's race. They failed, however, to find out the eater of sacrificial libations who had concealed himself by merging his self into self.[384] About this time, a frog, living in water, appeared on the surface thereof from the nethermost regions, with cheerless heart in consequence of having been scorched by the energy of Agni. The little creature addressed the deities who had become penetrated with fear and who were all very eager to obtain a sight of the deity of fire, saying, "Ye gods, Agni is now residing in the nethermost regions. Scorched by the energy of that deity, and unable to bear it longer, I have come hither. The illustrious bearer of sacrificial libations, ye gods, is now under the waters. He has created a mass of waters within which he is staying. All of us have been scorched by his energy. If, ye gods, ye desire to obtain a sight of him,--verily, if ye have any business with him,--do ye go to him thither. Do, indeed, repair thither. As regards ourselves, we shall fly from this place, ye deities, from fear of Agni." Having said this much, the frog dived into the water. The eater of sacrificial libations learnt of the treachery of the frog. Coming to that animal, he cursed the whole batrachian race, saying, "Ye shall henceforth be deprived of the organ of taste."
