Funky Cat Maybe
[イメージ曲]歌：??

Even today

1st the end trouble You studied many
一日終わって今日もごくろうさま
Even tomorrow will make efforts
いっぱい勉強したね、明日も頑張ろう

Day sets and the time of the under school
日が沈んで下校の時間
Stepping on the shadow that grew I will come back cheerfully
伸びた影踏んで楽しく帰りましょう

However, I wait a little bit I see the surroundings Is not it strange something?
でもちょっと待って　周りを見て　何か変じゃないか？
The thing that attached to the head be what?
その頭についている物は何
The thing that protruded prettily be what?
その可愛く飛び出た物は何

Be careful! fellows are coming to there
気をつけろ、奴らはそこまで来ているぞ
Escape early! fellows are next to you
早く逃げろ、奴らは君の隣に居るぞ
Do it! Attach the ear of a cat!
さあ、猫耳を付けろ！
Do it! Attach the ear of a cat!
さあ、猫耳を付けろ！

Raise both hands! (highly toward the sky)
両手を挙げろ！　　（高く空に向けて）
Raise both hands! (More highly toward the sky)
両手を挙げろ！　　（もっと高く空に向けて）
