The toy surprised me!! The toy surprised me!

The toy surprises me!! The toy surprises me!!

(1) "Toy" is a singular noun, but "surprise" is a plural verb. (2) If you're instead describing a specific past event where the toy surprised you, you would use the past tense, as UmbrellaTerms has suggested: "The toy surprised me!!"

TheOPTION A: A toy surprised me!! OPTION B: A Surprising Toy OPTION A: A toy surprised me!! OPTION B: A Surprising Toy

OPTION B is better than OPTION A.

My children got a real bigbig and realistic bug toy. My children got a big and realistic bug toy.

(1) リアル: realistic. "Real big" will be mistaken for the colloquial form of "really big". (2) For some reason, "big and realistic" sounds much better to me than "realistic and big". I suspect it has something to do with the rhythm of the sentence. Of course, the latter is by no means wrong, but I just thought I'd let you know this anyway.

MYesterday, my children got a real big bug toy. Yesterday, my children got a real big bug toy.

提案：文章をより自然にするために、「昨日」や「今朝」などの時間を示す語句を追加してください。（読者はいつこの出来事が起こったのかを知りたいと思っています。） SUGGESTION: Add a time marker such as "Yesterday" or "This morning" to make the passage more natural. (Readers want to know when this happened.)

My children got a real big bug toy. My children got a big bug toy.

They pastedstuck it onto the mirror in the washroom. They stuck it onto the mirror in the washroom.

"pasted" works too, but "stuck" fits better in this case.

They pasted it on(to) the mirror in the washroom. They pasted it on(to) the mirror in the washroom.

UmbrellaTerms suggested "stuck on(to)" in place of "pasted on(to)", and I agree that the former might be the more appropriate word here. When I see the verb "paste", I typically think of someone sticking a thin piece of paper onto a surface using paste (a type of adhesive). On the other hand, "stick" is a much more general term, and can be used whenever you're attaching two objects together. That being said, even if you used "paste" instead of "stick", you'd still be understood perfectly fine!

When I gowent to the washroom while still groggy from sleep in the morning, I′m was really surprised!! When I went to the washroom while still groggy in the morning, I was really surprised!!

Whenever I go to the washroom while still groggy (from sleep) in the morning, I′m really surprised!! Whenever I go to the washroom while still groggy (from sleep) in the morning, I′m really surprised!!

(1) "From sleep" might be redundant, so you can consider omitting it. (2) You didn't use the past tense in the native text, so I assume you're not describing any specific past event. If you're describing a general pattern or occurrence, you should use the word "whenever".

注：過去形に変更してください。これは過去の出来事ですよね？ NOTE: Change to past tense. This is a past event, right?
