Caleb Schwab, the 10-year-old boy killed in a horrific water slide accident at the Schlitterbahn Water Park in Kansas City, knew there was a heaven and he knew exactly what it would be like there: lots and lots of chocolate milk.

Caleb’s friend Jack Sloan, 10, told his mother Robin Sloan about the conversations the two boys shared during their days attending Sunday School together at LifeMission Church in Olathe, Kansas.

“They talked about heaven,” Robin Sloan tells PEOPLE. “Jack loved chocolate milk. [He and Caleb] said there would be endless amounts in heaven.”

Caleb died Sunday while on the Verruckt (German for “crazy” or “insane,”) the world’s tallest water slide.

While the cause of his death is still pending, funeral arrangements were released. Visitation for Caleb will be Thursday from 6 to 8 p.m. at LifeMission Church in Olathe while a memorial service will be held Friday at 2 p.m., according to a Gofundme site created to help pay for the funeral.

His pal Jack, who will be a fifth grader, described Caleb as a “nice, happy kid,” Robin Sloan says.

“He was a hugger,” she says of Caleb. “He always hugged Jack whenever he saw him.”

Caleb loved sports in general and baseball in particular, Jack relayed.

Caleb also was devout.

“Caleb knew Jesus, and he’s there [in heaven,]” Sloan says. The two friends didn’t doubt the power of prayer. “They knew if someone was sick, they would just pray for them,” she says.

Sloan said it was difficult having to break the news of Caleb’s death to Jack and her other two kids.

“I told him there was an accident at Schlitterbahn and someone got hurt,” she says. “He asked if they were going to make it and I said no.”

When Jack learned it was Caleb who died, he was devastated. “It’s hard for him,” Sloan says. “He was in his room sad and crying.”

Prayer is offering some comfort to her family, she said, and Jack is taking solace in his faith.

“He knows that he will see him again,” Sloan says. “He said, ‘It’s not forever sad, it’s just temporary sad.'”

At school, Caleb, who would have started fifth grade next week, was known among teachers as “kindhearted, joyful and inquisitive,” Rick Lukianuk, chief administrator at Heritage Christian Academy in Overland Park, Kansas, tells PEOPLE.

“Teachers would rave about the fact that he would try to clean something up even if it wasn’t his mess,” Lukianuk says.

Caleb also was a good sport on the field, as a baseball player with his little league team, the Mudcats. “If he didn’t get a hit he didn’t go and pout,” Lukianuk says. “He would just say, I can’t wait to try again.”

Caleb loved recess, playing tag and dancing around the classroom, he says. He and some buddies also liked drawing cartoons of superheroes but would “make themselves the heroes saving the world,” he said.

The grade-schooler also had a contemplative side, he says. Last year, students were saddened when a teacher and mother of one of his classmates died at the beginning of the year. “He asked, ‘Why would a bad thing happen to a good person,'” Lukianuk recalls.

The administrator told him, “Good can come out of bad,” and now Caleb will also provide that heartbreaking lesson to his fellow classmates, he says. “We’re letting kids know that God wants your life to be joyful and to care for others as Caleb did,” Lukianuk says.
