Thanks for helping me out. (pun: '10 ants')
Standard humorous spelling using kanji for 'ant' and Arabic numerals.
Variant using kanji numerals; less common in casual writing.
Katakana spelling for 'ant', often used in informal or playful contexts.
A pun on ありがとう (thank you), created by breaking it into あり (ant) + が + とう (ten), and then replacing とう with 十匹 (じゅっぴき, counter for ten small animals). The phrase literally means '10 ants'.
