If Mossborn Hydra somehow enters at the same time as one or more other lands you control, its last ability triggers for each of those lands.

A landfall ability doesn't trigger if a permanent already on the battlefield becomes a land.

2024-11-08wotc

To double the number of +1/+1 counters on Mossborn Hydra, put a number of +1/+1 counters on it equal to the number it already has. Other cards that interact with putting counters on it will interact with this effect accordingly.
