before the experiment:
looks like a green frog-like character in a similar costume:
green head;
large expressive eyes;
yellow crown with green details;
black or very dark suit;
green tie;
white shirt;
white stripes on the sleeves;
two gold buttons on the chest.
his character before:
• Emotional and open: He is not afraid to show his feelings, often acts on intuition and reacts violently to what is happening.
• Friendly and caring: In stories, he often acts as the side that tries to smooth things over, show empathy and support.
• Vulnerable, but stubborn: He is easily hurt or offended (especially by barbs from Grox), but he is still attached to his “friend” and does not abandon him in trouble.
after the experiment:
Appearance: Froggy's usual skin.
Clothing: regular shirt and tie, no jacket.
Face: calm, almost emotionless.
Eyes: attentive, suspicious look.
Skin: light green, slightly pale.
Neck: medical sensors.
Hands: traces of experiments carried out.
Behavior: quiet, observant, secretive.
character:
Complete emotional deafness and invulnerability. In his normal state, Froggy can be easily hurt or offended by words, but in his rage mode, he is completely insensitive to other people's emotions and barbs.
Seriousness and primitive cruelty

His friendly hyperactivity turns into a concentrated, frightening seriousness.
Loss of control and cannibalism (wild hunger)

This condition is fueled by a virus, causing Froggy to behave like a dangerous predator. (He doesn't use Grox catchphrases.) While enraged, he can speak, but in a harsher, louder, and slightly lower voice.
