This is a very weak enemy, due to its low stamina and attack strength. Its short attack range makes it vulnerable to attacks by the player's cats. Usually appears in clusters, or as peons throughout the game.
Interestingly, this enemy is set as the boss in many the Stories of Legend stages. It can be assumed that at that point, a boss shockwave was needed, and if there are 2 or more threatening enemies, then the shockwave is given to a suicidal squirrel.
Just kill this enemy like you would with any peon. It is very easy to kill, so no strategy is required. However, in levels like Apple Bobbing Ocean, it will get a major buff, so meatshield all you can and try to kill them quickly.
She speaks an old English dialect (?)
No, seriously, it sounds like English, but it's too hard to understand what she says.
A squirrel who speaks in its own creative style of English. Its pronunciation sounds like English, but I can't understand it. Usually found working at the English school down by the station.
Time between attacks
110 (single target)
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
*Time between attacks is the time of the attack from the motion end until the next attack motion start
References the English conversation schools commonly found outside train stations across Japan. None of them have a squirrel as a mascot however, although arguably the most infamous chain did have a rabbit thing.
