Strange Midrashim about Frogs

When the Torah describes the plague of frogs, we find two strange Rashis: 1) in 7:29, he says that the frogs went into the Egyptians’ bellies and croaked. 2) in 8:2, he says that it started with one frog, which continued to multiply as they hit it. Are these meant to be literal? This episode tries to: explain these midrashim, look more closely at the pesukim themselves, and get some deeper insights into this plague.
