I personally find the names intuitive but the meanings are idiomatic and perhaps overly cute/clever for non-native speakers. Cluck also means to “wag one’s tongue.” Croak is also to die; even used as a verb to kill. Confess is to explain a sin at length or in detail. Alliteration is a kind of mnemonic.

Update, typo corrected via hippo. Life imitates me imitating life -> :P s/tonue/tongue/;
