The crocodile is a newly added match 3 game element. Here, players would need to feed the crocodile by matching pieces next to it.
When players first make a match next to the crocodile, it opens its mouth. If a second match is made near the crocodile, it gets even hungrier and opens its mouth wider.
Making the third match near the crocodile causes it to eat all the pieces of a random color and then disappear from the board.
