The Mockiwi family is a family of avian-like creatures, that according to Olimar, could fly, but lost their ability through evolution. There are various species of Mockiwi, but only 3 Mockiwi are currently known. These are:
The Mockiwi is a creature that appears in Hey! Pikmin. They are yellow, avian-like creatures with bodies shaped similar to a bulborb, with a short, wide beak, large brown eyes, and two small vestigial wings. The Mocikiwi are aggressive creatures that attack Pikmin on sight. Like bulborbs from other games, the best strategy is to attack them from behind. They drop 2 sparklium upon death.
Crested Mockiwis are also from Hey! Pikmin, and are distinctive for their feathered crests and purple body. Apart from that, they're identical in behavior to a normal Mockiwi, but they can shake off Pikmin. They also drop 2 Sparklium.
The Elongated Crushblat is a very tall, yet docile species of Mockiwi with very long, thin legs evolved for access to food in hard-to-reach places. Unlike other Mockiwi, it doesn't intentionally pursue Pikmin, more rather stepping on them accidentally as it moves around. In order to defeat one, throw your Pikmin at the feathers on its knees until it crouches down, and then throw your Pikmin onto its back. It drops 20 sparklium upon defeat, and there's only one throughout the whole game.
